utils: raspberrypi: ctt: Adapt tuning tool for both VC4 and PiSP

Browse source 
The old ctt.py and alsc_only.py scripts are removed.

Instead of ctt.py use ctt_vc4.py or ctt_pisp.py, depending on your
target platform.

Instead of alsc_only.py use alsc_vc4.py or alsc_pisp.py, again
according to your platform.
