please add systemd unit file

please add a native systemd unit file

I see that /etc/init.d/shellinabox is really complex.

Here is the service provided by Arch that can be used as 
a starting point.

This should go in /lib/systemd/system/shellinabox.service
or in /etc/systemd/system/shellinabox.service during tests.
