kunit: kasan_test: disable fortify string checker on kmalloc_oob_memset
Similar to commit 09c6304e38e4 ("kasan: test: fix compatibility with
FORTIFY_SOURCE") the kernel is panicing in kmalloc_oob_memset_*.
This is due to the `ptr` not being hidden from the optimizer which would
disable the runtime fortify string checker.
kernel BUG at lib/string_helpers.c:1048!
Call Trace:
[<00000000272502e2>] fortify_panic+0x2a/0x30
([<00000000272502de>] fortify_panic+0x26/0x30)
[<001bffff817045c4>] kmalloc_oob_memset_2+0x22c/0x230 [kasan_test]
Hide the `ptr` variable from the optimizer to fix the kernel panic. Also
define a memset_size variable and hide that as well. This cleans up the
code and follows the same convention as other tests.
