When parameters are sent the PSP returns back it's own signature
for the application to verify the authenticity of the result.
Display this signature to the caller instead of the one the caller
sent.

crypto: ccp - Fix DBC sample application error handling2023-09-15T10:29:45ZMario Limonciello2023-08-29T15:07:57Zurn:sha1:70f242c1933e9e881c13c31640bb6d56e8b7e738
The sample application was taking values from ioctl() and treating
those as the error codes to present to a user.
This is incorrect when ret is non-zero, the error is stored to `errno`.
Use this value instead.

Add a small shared library that demonstrates the usage of the
IOCTL interface. This library can be linked to but, is
intended to be loaded and used by higher level languages
