kasan: only build init.c for software modes
This is a preparatory commit for the upcoming addition of a new hardware tag-based (MTE-based) KASAN mode. The new mode won't be using shadow memory, so only build init.c that contains shadow initialization code for software modes. No functional changes for software modes.
