[gnome-software] Do not hardcode the application name

[Richard Hughes <rhughes src gnome org>]

commit c1f5e4b9d1a0df697816e3bf1d8c961fc65a8ecf

    Do not hardcode the application name
    
    Various downstream distros rename 'GNOME Software' to different things, for
    various reasons.
    
    Allow the application name to be changed by patching the .desktop file in one
    place rather than having to patch various places in the source file.
