svn commit: r321702 - head/tests/sys/geom/class/gate

Log:
  Load geom_gate(4) if necessary before running tests; skip if it can't be loaded
  
  The test code prior to r311893 loaded geom_gate at test start if necessary and
  skipped the tests if it couldn't be loaded.
  
  The ATF-ifcation of this test done in r311893 unfortunately dropped this
  functionality.
  
  This change restores the geom_gate module load and skips the test(s) if unavailable
  in an ATF-like way.
