[gnome-software/gnome-3-20] Use a background PackageKit transaction when downloading upgrades

[Richard Hughes <rhughes src gnome org>]

commit b67a8e0456ff078d82e1bceb59011d8daead24f9
Author: Richard Hughes <richard hughsie com>

    Use a background PackageKit transaction when downloading upgrades
    
    This means any other foreground PackageKit transaction from any user will
    auto-cancel the background task and it will *not* be restarted automatically.
