    app-window: Use GtkFileChooserNative
    
    These changes are necessary in order to make Boxes consume the
    Flatpak file chooser portal.
    
    FileChooserNative is an abstraction of a file chooser dialog that
    uses the running platform's native file chooser dialog. Although
    Boxes is Linux-exclusive, we need FileChooserNative in order to
    consume the org.freedesktop.portal.FileChooser portal whenever it
    is available on the session bus.
    
    This way we bring up an out-of-process file chooser that enables
    the user to select a file to be used in Boxes without giving us
    access to the filesystem out of the Flatpak sandbox.
