Invisible symbols in sssd upstart config causes sssd to not start if /bin/sh is a link to /bin/bash

I've committed a bug for Ubuntu today. Hope they fix that soon, since we have not so much time before migrate all users from 10.04 to 12.04.

UPD: Quite impressive. It took only 2 hours after bug commit to release a fix! Bravo!
