selftests/nolibc: Fix build with host headers and libc
Many systems don't have strlcpy() or strlcat() and readdir_r() is
deprecated. This makes the tests fail to build with the host headers.
Disable the 'directories' test and define strlcpy(), strlcat() and
readdir_r() using #defines so that the code compiles.
Fixes: 6fe8360b16acb ("selftests/nolibc: also test libc-test through regular selftest framework")
