    worker: don't run shell scripts for program sessions
    
    GDM uses a worker to manage PAM for user sessions and
    greeter sessions. For the latter case we shouldn't run
    the various Pre/Post scripts, but commit
    Sb48a305e71637181975fc7ec479a71079b6fbc broke that.
    
    This commit changes the code to prevent those scripts
    from getting run again.
