feat: enable proper systemd support in Docker tests (#1373)

- Replace the `sed` hack that disabled `systemctl` commands with proper
systemd support in Docker containers
- This allows testing the actual `systemctl` commands used by the
install script
- No more manual workarounds for starting OpenVPN/Unbound services
