Subject: [PATCH] Overhaul the systemd uint configuration file

We have no sbbs man page (that I know of).
The SBBSROOT env var isn't used anywhere.
NotifyAccess is required for the (new to v3.20) systemd integration support
We can just use the AmbientCapbilities to set the bind capability now
Set the open file limit to something huge (10000 files should be enough)
Update the instructions/comments.
