Several foundation channels have moved to new names and the old ones
have been set private to ensure new joins get correctly forwarded.
Unfortunately this means that our check access script is unable to
correctly determine permissions as it does not use a privileged
account and instead receives an access denied error from ChanServ
when trying to perform an access list call on each of them. Remove
these channels so we'll stop blocking merge of unrelated changes in
Also take gerritbot out of #openstack-ptg so accessbot won't insist
on it being listed.
