Remove old systemd service checks

These are not even caused by Archlinux, but by running buggy Ansible on old Ubuntu
while targeting modern servers (like Archlinux, but also others, ..).

We shouldn't employ ugly workarounds like this. We should tell people to
avoid running buggy Ansible or bad distros like Ubuntu, even.
