infra: adjust the containers to use full systemd

The systemd-standalone-sysusers package, which is pre-installed in the containers,
conflicts with systemd. Since Anaconda requires systemd as a dependency,
this conflict prevents installation during tests.

This update ensures that containers use the full systemd package to resolve the dependency issue.
