Remove the -T option so it iss possible to run cvsweb 2 on Perl 5.8
which has more strict taint checks.

This is a temporary stopgap while upgrading to perl 5.8 and migrating
to cvsweb 3 to get around the catch-22 that cvsweb 3 requires perl
5.8, and perl can't be upgraded to 5.8 if it breaks cvsweb.
