Yeoreum Yun 2616a517f9 kunit: kasan_test: disable fortify string checker on kasan_strings() test
commit 7a19afee6f upstream.

Similar to commit 09c6304e38 ("kasan: test: fix compatibility with
FORTIFY_SOURCE") the kernel is panicing in kasan_string().

This is due to the `src` and `ptr` not being hidden from the optimizer
which would disable the runtime fortify string checker.

Call trace:
