channeld: reject closing_complete and closing_sig with a clear error

Browse source 
When `option_simple_close` is negotiated the master launches `simpleclosed`
after `channeld` exits, so `closing_complete` and `closing_sig` should never
arrive inside `channeld`.  Add stubs that call peer_failed_warn() with an
informative message rather than hitting the default unknown-message path.
