Fix a mod_cgid problem that left daemon processes stranded

in some server restart scenarios.

It relied on getting SIGHUP to die, but it wasn't careful
about establishing the SIGHUP handling it needed so after
apachectl restart, SIGHUP was ignored since the new cgid
daemon process inherited a signal(SIGHUP,SIG_IGN) done by
the MPM during its restart logic.
