testcases: Make camera postprocessing conditional on camera testplan

Apply camera-specific CDT replacement only when running camera tests
on rb3gen2-core-kit to prevent unnecessary postprocessing overhead on
non-camera test cases. This allows boot, audio, and other validation
tests to run efficiently without camera-specific image modifications
while ensuring camera tests receive proper vision kit CDT configuration
for rb3gen2-core-kit target.
