ANDROID: kbuild: disable LTO_CLANG with KASAN 



Using LTO with KASAN currently results in "inlinable function call
in a function with debug info must have a !dbg location" errors for
memset and several of the __asan_report_* functions.

As combining these options doesn't provide significant benefits,
this change disables LTO_CLANG when KASAN is selected.
