lib/_emerge/actions.py: drop custom clang identification

drop this bit, because:
- there are no native Clang toolchains in use in Prefix currently
- it isn't guaranteed to be correct
- we can just rely on PATH because this isn't anything but cosmetics
- it is cosmetics, it isn't necessary for Prefix to operate correctly
- it is disputed to be correct in the first place:
