add optional AmbientCapabilities to systemd unit

Browse Source 
If a user wants to bind to a privileged port (<1024) our current systemd unit fails to provide enough capabilities to endlessh binary.

So, a user can modify `/etc/endlessh/config` to have `Port=22` or similar and then check out the systemd unit to enable the extra attribute.
