Remove libcameraservice and libcamera_client from base_system

Libcameraservice is only used by cameraserver, and is explicitly listed
as a dependency.  Libcamera_client is used by multiple places, but each
of them lists it as a depedency as well, so it's not needed here.

Removing the unused 64-bit version of libcameraservice will save ~2 MB
on the system partition.
