Subject: [PATCH] Post an error if a fork mode is set and fork is unavailable

The default fork mode if fork is unavailable is CK_NOFORK.
Someone trying to set a fork mode without fork available will
only result in failures running tests. Posting an error up
front before tests are run makes more sense.
