ANDROID: Allow HAS_LTO_CLANG with KASAN_HW_TAGS

Normally enabling KASAN will disable LTO_CLANG due to an old compiler
bug, however it's unlikely such old compilers would be used with the new
KASAN_HW_TAGS feature which is only usable on new architectures, so
relax the check if KASAN_HW_TAGS is enabled.
