channeld: allow WIRE_ANNOUNCEMENT_SIGNATURES before funding_locked.

Browse source 
LND does this, and we get upset with it.  I had assumed we would only
do this after funding_locked (since we don't consider the channel
shortid stable until that point), but TBH 6 confirms is probably
enough.

Fixes: #1985
