connectd: Pass the init_featurebits down to connectd and use in init

Browse Source 
The `init_featurebits` are computed at startup, and then cached
indefinitely. They are then used whenever a new `init` handshake is performed.

We could add a new message to push updates to `connectd` whenever a plugin is
added or removed, but that's up for discussion.
