Don't kill Runner.Listener when steps running (#30)

Because of the `--once` flag we already pass to the deamon, _if_ there
were any jobs running, then the main actions-runner deamon (the
Runner.Listener process) will shut it self down once it's _actually_
finished.

So we want to avoid the `pkill Runner.Listener` in the case when a step
was executing, as otherwise we will likely kill the deamon before it has
a chance to complete the job/report back to GitHub/run the next step.
