selftests/mm: only prepare ptrace_scope when memfd_secret is selected
The memfd_secret setup clears ptrace_scope whenever its test binary is
executable, even when a different category was selected. run_test()
filters the test invocation, but it does not protect the preceding setup.
Check the category selection before entering the memfd_secret block so
running unrelated categories does not change ptrace_scope. Keep the
existing executable check and the behavior when memfd_secret is selected.
