Cirrus: More podbot/success improvements

* Fix one disused and two missing required env. vars.
* Slightly optomize processing of commit-author names
* Fix problem of printing duplicate author names when there are multiple
commits.
* Fix bot's IRC connection timeout too short.
* Add a single retry of IRC connection after 5-second delay.
