mkdir -p creates paths that are bound to user's settings and therefore
can lead to different file mode bits of the base paths accross different
machines.
Use install instead, as this tool is not prone to such behavior.

File: entries in the WHENCE file overwrite existing files in the target
directory, however, Link: entries are skipped if the file exists in the
target directory. This can cause issues if the Link: entry is updated, but
the target directory contains an old symlink. Do not skip writing Link:
entries if the file exists, always create the symlink. This matches the
behavior of File: entries and ensures symlinks will contain values from
the WHENCE file.

Rather than require symlinks to be created in the filesystem and have
duplicate Link: entries in the WHENCE file, make copy-firmware.sh create
the symlinks on the fly.

The current make-install procedure leaves lots of garbage files that
aren't really firmware files in /lib/firmware.

Instead of copy-all-and-prune approach, copy only the listed files and
links in WHENCE by make-install for assuring only the proper firmware
files.
