selftests/mm: workaround no way to detect uffd-minor + wp
Userfaultfd minor+wp mode was very recently added. The test will fail on
the old kernels at ioctl(UFFDIO_CONTINUE) which is misterious.
Unfortunately there's no feature bit to detect for this support.
Add a hack to leverage WP_UNPOPULATED to detect whether that feature
existed, since WP_UNPOPULATED was merged right after minor+wp.
