Marco Elver 85f195b12d kasan: test: fix test for new meminstrinsic instrumentation
The tests for memset/memmove have been failing since they haven't been
instrumented in 69d4c0d321.

Fix the test to recognize when memintrinsics aren't instrumented, and skip
test cases accordingly.  We also need to conditionally pass -fno-builtin
to the test, otherwise the instrumentation pass won't recognize
memintrinsics and end up not instrumenting them either.

Fixes: 69d4c0d321 ("entry, kasan, x86: Disallow overriding mem*() functions")
