devel/cvs: enslave devel/cvs+ipv6 to avoid bitrot

- devel/cvs: allow slave ports (?= vars)
- devel/cvs: define CONFLICTS against the slave and -devel
- devel/cvs: adjust for easier patching source (i.e. no ../cvs/ prefix)
- devel/cvs+ipv6: move most logic as IPV6 option to devel/cvs
- devel/cvs+ipv6: don't define HAVE_GETGROUPS twice or unused ENABLE_IPV6
- devel/cvs+ipv6: drop devel/cvsnt from CONFLICTS after 4.6 years being gone
- devel/cvs+ipv6: bump PORTREVISION for changes inherited from devel/cvs
- Convert CONFLICTS into CONFLICTS_INSTALL
