fix(gluetun): add OpenVPN process user and cleanup stale config

- Add OPENVPN_PROCESS_USER=root, PUID=0, PGID=0 to default .env to prevent gluetun from injecting 'user' directive into target.ovpn which causes 'Unrecognized option' errors on Debian - Add ExecStartPre to remove stale /etc/openvpn/target.ovpn before start - Fixes #12988
