selftests/mm: use pkey_assert on clone_raw failure in pkey test

Browse Source 
Use pkey_assert(0) instead of perror("clone") when clone_raw() fails.  The
old path only printed an error and continued; the test now exits via
pkey_assert() on failure so it does not hang or proceed with an invalid
child.
