gossipd: prune announced-but-not-updated channels eventually.

Browse Source 
We currently give them a free pass.  The simplest fix is to give them
an old timestamp on initialization.

We still skip unannounced channels, on the assumption that they're
ours.  And we set the last_update_timestamp to -1 when we convert to
gossip_getchannels_entry to indicate no update.

This breaks the DEVELOPER=1 pruning test, since we hardcode the 1
week timeout.  That's fixed in the next patch.
