Since arch_pick_mmap_layout() is an inline for non-MMU systems, disable this test there.

2024-06-14usercopy: Convert test_user_copy to KUnit testKees Cook
Convert the runtime tests of hardened usercopy to standard KUnit tests. Additionally disable usercopy_test_invalid() for systems with separate address spaces (or no MMU) since it's not sensible to test for address confusion there (e.g. m68k).
