[Kai Willadsen <kaiw src gnome org>]

commit 4198ac00998abd44d4edce9712e24285921ce3a7

    Fix the Flatpak build manifest
    
    There's no need for a Makefile, now that Flatpak has the "simple"
    buildsystem.
    
    In addition, Meld requires Python 3, so let's move the Flatpak build to
    that.
