Paolo Bonzini 4848cb3d9f test: execute g_test_run when tests are skipped 
Sometimes a test's main() function recognizes that the environment
does not support the test, and therefore exits.  In this case, we
still should run g_test_run() so that a TAP harness will print the
test plan ("1..0") and the test will be marked as skipped.
