gossip_store: remove now-redundant push bit

Browse source 
The push bit was convenient for connectd to send our own gossip
to peers upon connecting by naively traversing the gossip_store
and sending anything flagged `push`.  This function is now
performed by gossipd leaving no use for the push bit.

Changelog-Changed: `gossipd`: gossip_store PUSH bit is no longer set.
