I think we might as well just disable KASAN for COMPILE_TEST entirely
- not artificially limit it to just x86-64.

Apparently it was effectively disabled anyway due to that SLUB_TINY
interaction, so while it would be nice to have bigger build coverage,
clearly we haven't had it before, and it causes problems.
