Make sure pagemap_ioctl exits with an appropriate value:

* If the tests are run, call ksft_finished() to report the right
  status instead of reporting PASS unconditionally.

* Report SKIP if userfaultfd isn't available (in line with other
  tests)

* Report FAIL if we failed to open /proc/self/pagemap, as this file
  has been added a long time ago and doesn't depend on any CONFIG
  option (returning -EINVAL from main() is meaningless)
