[gnome-software] Use proxy settings

[Matthias Clasen <matthiasc src gnome org>]

commit 75e1e9066d90e09274197b0d582adc31be1b94cd
Author: Matthias Clasen <mclasen redhat com>
Date:   Sat Nov 2 00:21:31 2013 -0400

    Use proxy settings
    
    This moves more functionality from the gsd updates plugin.
    
    We pass the session proxy settings to PackageKit, so it can
    use the right network for downloading.
