In the same way as for other similar files, mark as ghost the new file
generated by depmod for configured weak dependencies for modules,
modules.weakdep, so that although it is not included in the package,
claim the ownership on it.

After 8d1001f7 (kbuild: rpm-pkg: fix build error with CONFIG_MODULES=n),
the following warning "warning: File listed twice: *.dtb" is appearing for
every dtb file that is included.
The reason is that the commented commit already adds the folder
/lib/modules/%{KERNELRELEASE} in kernel.list file so the folder
/lib/modules/%{KERNELRELEASE}/dtb is no longer necessary, just remove it.

When CONFIG_MODULES is disabled, 'make (bin)rpm-pkg' fails:

  $ make allnoconfig binrpm-pkg
    [ snip ]
  error: File not found: .../linux/rpmbuild/BUILDROOT/kernel-6.10.0_rc3-1.i386/lib/modules/6.10.0-rc3/kernel
  error: File not found: .../linux/rpmbuild/BUILDROOT/kernel-6.10.0_rc3-1.i386/lib/modules/6.10.0-rc3/modules.order

To make it work irrespective of CONFIG_MODULES, this commit specifies
the directory path, /lib/modules/%{KERNELRELEASE}, instead of individual
files.

However, doing so would cause new warnings:

  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.alias
  warning: File listed twice: /lib/modules/6.10.0-rc3-dirty/modules.alias.bin

These files exist in /lib/modules/%{KERNELRELEASE} and are also explicitly
marked as %ghost.

Suppress depmod because depmod-generated files are not packaged.

Some architectures, like aarch64 ones, need a dtb file to configure the
hardware. The default dtb file can be preloaded from u-boot, but the final
and/or more complete dtb file needs to be able to be loaded later from
rootfs.

Add the possible dtb files to the kernel rpm and mimic Fedora shipping
process, storing the dtb files in the module directory. These dtb files
will be copied to /boot directory by the install scripts, but add fallback
just in case, checking if the content in /boot directory is correct.

Mark the files installed to /boot as %ghost to make sure they will be
removed when the package is uninstalled.

Tested with Fedora Rawhide (x86_64 and aarch64) with dnf and rpm tools.
In addition, fallback was also tested after modifying the install scripts.

Installing the kernel package is fine, but when uninstalling it, the
following warnings are shown:

  warning: file modules.symbols.bin: remove failed: No such file or directory
  warning: file modules.symbols: remove failed: No such file or directory
  warning: file modules.softdep: remove failed: No such file or directory
  warning: file modules.devname: remove failed: No such file or directory
  warning: file modules.dep.bin: remove failed: No such file or directory
  warning: file modules.dep: remove failed: No such file or directory

  warning: file modules.builtin.alias.bin: remove failed: No such file or directory
  warning: file modules.alias.bin: remove failed: No such file or directory
  warning: file modules.alias: remove failed: No such file or directory

The %preun scriptlet runs 'kernel-install remove', which in turn invokes
/usr/lib/kernel/install.d/50-depmod.install to remove those files before
the actual package removal.

RPM-based distributions do not ship files generated by depmod. Mark them
as %ghost in order to exclude them from the package, but still claim the
ownership on them.

The new installkernel application that is now included in systemd-udev
package allows installation although destination files are already present
in the boot directory of the kernel package, but is failing with the
implemented workaround for the old installkernel application from grubby
package.

For the new installkernel application, as Davide says:
<<The %post currently does a shuffling dance before calling installkernel.
This isn't actually necessary afaict, and the current implementation
ends up triggering downstream issues such as
https://github.com/systemd/systemd/issues/29568
This commit simplifies the logic to remove the shuffling. For reference,
the original logic was added in commit 3c9c7a14

("rpm-pkg: add %post
section to create initramfs and grub hooks").>>

But we need to keep the old behavior as well, because the old installkernel
application from grubby package, does not allow this simplification and
we need to be backward compatible to avoid issues with the different
packages.

Mimic Fedora shipping process and store vmlinuz, config amd System.map
in the module directory instead of the boot directory. In this way, we will
avoid the commented problem for all the cases, because the new destination
files are not going to exist in the boot directory of the kernel package.

Replace installkernel tool with kernel-install tool, because the latter is
more complete.

Besides, after installkernel tool execution, check to complete if the
correct package files vmlinuz, System.map and config files are present
in /boot directory, and if necessary, copy manually for install operation.
In this way, take into account if  files were not previously copied from
/usr/lib/kernel/install.d/* scripts and if the suitable files for the
requested package are present (it could be others if the rpm files were
replace with a new pacakge with the same release and a different build).

Tested with Fedora 38, Fedora 39, RHEL 9, Oracle Linux 9.3,
openSUSE Tumbleweed and openMandrive ROME, using dnf/zypper and rpm tools.
