Yeoreum Yun a7f7d4223f kunit: kasan_test: disable fortify string checker on kasan_strings() test 
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:
  __fortify_panic+0x10/0x20 (P)
