fedora-comon: Update default package set

* Install `system-upgrade` plugin for `dnf`, since we'll almost always
  want this in order to be able to update hosts
* Do not install _sshca-cli-systemd_; this package has been deprecated
  and removed in favor of setting up the systemd units from Ansible
* Install _python3-libdnf5_, as this is required by Ansible and will be
  installed by it later, so we can save a bit of time by always having
  it installed.
