Merge 8.2001.0-1 from Debian

[Christian Ehrhardt ]

Debian is at 8.2001.0-1 which among many fixes by the new upstream changes also resolved python3 issues.

This is a year of extra fixes that would be nice going into a new LTS.

Important: I think I might be able to prepare the merge but I'm unavailable next week so I'd need someone else to upload and drive/attend the proposed migration.

This bug was fixed in the package rsyslog - 8.2001.0-1ubuntu1
