[pkg-go] Bug#1104513: Podman services stop but don't restart during package updates

[José Martínez]

Package: podman
Version: 5.4.2+ds1-1

The podman package maintainer scripts will stop podman systemd
services during a package update but never restart them afterwards.

This is surprising for administrators that have enabled any of these
services either manually or from a previous version that had them
enabled by default. Administrators will now see podman services stop
every time a podman package update happens and will have to restart
them manually. The services remain enabled so a reboot would also
restart them. If a service is running at package update time it should
remain running afterwards.

This behavior was introduced in 5.4.1+ds1-1.

Here is an example of enabling a podman service and simulating a package update:

---------------

$ sudo apt install podman
Installing:
  podman

  docker-compose
