Kanshi used to be restarted every time river would be reloaded.
This is not desired however, as restarting river would also
kill the kanshi daemon, and subsequently reload it, reseting
any custom kanshi output layouts or options set.
With this commit kanshi only gets started if it is not already
running through river (i.e. on first boot most of the time).
