yep, I should have given more details.
This behavior (starting the driver without -a and upsd being able to server
its data) which we'll call "unnamed ups", goes back to a time when we were
able to call "upsc localhost".

Now, users are using the conf files, and upsdrvctl or drv -a. So the only
need to start the drv manually (without -a) is only for debug purpose.
Thus we don't have to care about upsd communication, and the socket filename
can be a dummy value. We only create it for compat...

So this new behavior becomes the standard.
