[gdm] slave: Don't set envvars in the slave

[Jasper St. Pierre <jstpierre src gnome org>]

    slave: Don't set envvars in the slave
    
    All the APIs we use take things explicitly, so we don't need these
    envvars. At the same time, lose the signal manipulation. The goal
    here is to integrate the slave back into the daemon process.
