crypto: ccp - Add a sample python script for Dynamic Boost Control

Dynamic Boost Control commands are triggered by userspace with
an IOCTL interface that userspace will prepare proper buffers
for a request.

To allow prototyping and testing this interface, add a python3
command line script that loads the dbc_library.so for utilizing
the IOCTLs.

The signature to use and UID are passed as arguments to this script.
