openingd: use peer_failed like normal instead of boutique negotiation_failed.

Browse source 
Because peer_failed would previously drop the connection, we had a
special 'negotiation_failed' message which made the master hand it
back to gossipd.  We don't need that any more.

This also meant we no longer need a special hook in read_peer_msg
for openingd to send this message.
