Drop #edeploy channel from statusbot config

I've confirmed with EmilienM in #tripleo that the edeploy project is
defunct and the #edeploy IRC channel is no longer in use. It was
registered on OFTC by a lone project contributor many years ago and
is not under our control, so we should not be running bots in it
anyway.
