x86: kmsan: don't rename memintrinsics in uninstrumented files
clang -fsanitize=kernel-memory already replaces calls to
memset/memcpy/memmove and their __builtin_ versions with
__msan_memset/__msan_memcpy/__msan_memmove in instrumented files, so
there is no need to override them.
In non-instrumented versions we are now required to leave memset() and
friends intact, so we cannot replace them with __msan_XXX() functions.
