Subject[PATCH v2 06/37] kasan: only build init.c for software modes
From
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.
