Do not send "buildbot went away" emails to the buildbot-status maling list
@ned-deily requested that the "buildbot went away" emails are not sent to the buildbot-status mailing list. Any objections?

I don't see the point of these emails. Please stop to send them :-)
They're supposed to only be sent when a worker suddenly disappears, not every time the master is restarted (and restarts have become rather more frequent of late :)). I've pinged buildbot/buildbot#4234 about it, but if there's no change then we might as well disable them to the list:
https://github.com/python/buildmaster-config/blob/f4ae6ba6a0fc787da5192a77c0f8be53adbd139b/master/custom/workers.py#L31
Removing settings.get("status_email", None) here would do it.
