Christian Decker 6e01f38d7d gossip: Use the custom gossip wire msg to wrap channel_announcements
This stores and reads the channel_announcements in the wrapping message which
allows us to store associated data with the raw channel_announcements.

The gossip_store applies channel_announcements directly but it also returns it,
and it gets discarded as a duplicate. In the next commit we'll have gossip_store
apply all changes, bypassing verification, so the duplication is only temporary.
