systemd: update for network-online.target for systemd >= 200 (rh #787314)

systemd's new network-online target abstracts the "wait until
networking is up" stuff, and NM-wait-online implements that
functionality.  Thus NM-wait-online should be ordered before
(and thus be a dependency of) network-online.
