    build: workaround for broken cleanup of flatpak.
    
    For some reason, the "cleanup" tag won't delete the files produced by
    the BaseApp inside the main GIMP manifest (I still need them for build,
    but want to delete them for runtime).
    This is a workaround to delete them with a few command lines for now.
    See: https://github.com/flatpak/flatpak/issues/1082
