* ansible-test - Replace Fedora 40 with 41
Also update other distro containers to remove unnecessary packages:
* apache2
* subversion
* ruby
* Fix subversion test on Ubuntu
Also remove obsolete vars files from subversion test.
* Skip dnf test on Fedora 41+
The dnf5 test is all that is needed.
* Support dnf5 for the package test
* Extend unix-chkpwd work-around for Fedora
* Enable Ubuntu 24.04 group 6 in CI
* Disable rootfull Podman on Ubuntu
* Disable unix-chkpwd AppArmor profile on Ubuntu for Fedora 40 tests
* Document AppArmor and rootfull issues
Also improve the ansible-test-container integration test:
- Add coverage for the no-probe code path.
- Add work-arounds for centos6 containers (to support backporting).
- Avoid systemd debug when the container doesn't use cgroup.
