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.

TODO: Switch these skip messages to g_test_skip() now that we do not
have to deal with broken gtester binaries anymore... (could be done in a
future patch, though)
