set SyslogLevel=debug for systemd service avoid journald 

This setting in combination with `MaxLevelStore=info` in `/etc/systemd/journald.conf`
will prevent Journald from being constantly filled by a considerable flow of
logs from beacon nodes and making debugging of other servics on the host harder.

Due to this `journalctl` will no longer show logs for the service.
