connectd: no longer stream our own generated gossip, let gossipd do it.

Browse source 
This removes the sweep logic as soon as they connect.  This should save
connectd a significant number of CPU cycles and make @whitslack finally
stop hitting me.

Changelog-Changed: `connectd` no longer sweeps gossip_store file when peer connects, saving CPU for large nodes.
