Ending support for EOL releases in XMLTV github CI workflow?

The issue with github actions/checkout@v4 raised,
in my mind, a bigger issue.

I think it may be time to consider removing EOL
distro releases from the XMLTV github workflow
(with the usual lag due to no one paying close
enough attention to EOL schedules).

While I certainly don't object to those who want to
run XMLTV on EOL OS's, I am also not personally
motivated to care if it fails to build/run there (if
anyone opens an issue on (say) Ubuntu 16.04,
I would ask them to provide a PR, as I would
almost certainly not be willing to spend time to
fix it myself ("He's dead, Jim")).

I think the CI workflow should primarily test
currently supported (by the upstream source)
OS distro versions, and as soon as a distro
marks a release EOL it acceptable to be
removed from the CI list.
