lib/test_kasan.c: add tests for several string/memory API functions
Arch code may have asm implementation of string/memory API functions
instead of using generic one from lib/string.c. KASAN don't see memory
accesses in asm code, thus can miss many bugs.
E.g. on ARM64 KASAN don't see bugs in memchr(), memcmp(), str[r]chr(),
str[n]cmp(), str[n]len(). Add tests for these functions to be sure that
we notice the problem on other architectures.
