run: prefix unit description with our own process name

Browse Source 
I think we should try to communicate clearly if something is a run0
session, or a systemd-run invocation. Hence, let's initialize the
description so that the command is prefixed by
program_invocation_short_name.

Effectively this means that our run0 sessions now appear as services
with a description of "[run0] -/bin/bash"
