Fix the configure script. If a either the mpmt_pthread or dexter MPM's

are chosen, the default CGI module is mod_cgid.  If any other MPM is
chosen, mod_cgi is the default.  I would rather have the maintainers for
other platforms change their own defaults, than make mod_cgid the default
on all threaded MPM's.
