Create xlxd.service and improve systemd integration

[fabianfrz]

run xlxd as xlxd user (needed to be created manually)
also add a task to keep the node alive (xlxapi)

alternative to #195

I suggest the unit files for xlxd.service and ambed.service have "Requires=network-online.target" otherwise xlxd will fail to start because the network interface is not configured with an ip address.

@DcnPat It already contains After=network.target - I guess that this should be enough. I would also appreciate it, if the project maintainers would react on this at some point.

I found After=network.target Results in failure to start because the interface was not up so xlxd could not open ports to listen on. There needs to be an actual IP address associated with the interface and it has to be up, hence network-online.target is needed.

Checked that the target exists, so we can add this directive to the server. You comment sounds like you deployed my changes on your server. How are they doing so far?
