Sync the code that sucks in rc.conf and friends with what's in rc.firewall6.  Specifically, don't do anything if [ -z ${source_rc_confs_defined} ].  Not doing this leads to a problem with dependencies: chkdepend will set, e.g., portmap_enable to YES if some service that needs portmap is enabled, but rc.network sources rc.firewall, which used to source defaults/rc.conf unconditionally, which would result in portmap_enable being set back to NO.
