Don't directly execute bash for single-user mode, as that has SELinux issues. (#540216, #584443, #585053)
If upstart directly runs bash for single-user mode, there's no way for SELinux to set the proper context (to distinguish it from other init scripts). Inserting a helper binary in the way allows for this. While we're changing this, we make it configurable so it's easily possible for people to use sulogin if they so desire.
