test: Ensure LIBCAMERA_BASE_PRIVATE isn't public

Browse source 
If LIBCAMERA_BASE_PRIVATE is ever exposed on the libcamera public dependencies,
then the private.h header protection will be circumvented.

Provide a test which will fail (at compile time) if the LIBCAMERA_BASE_PRIVATE
define ever leaks to the public dependencies.
