In the rc.d/localpkg New World Order, the apache.sh startup script may
be executed when the apache_enable and other config variables have
already been set, e.g. via /etc/rc.conf. In that case, load_rc_config
will not do anything at all, and the "defaults" set in the script will
override the user's settings. Fix this by honoring any previously-set
config variables.
