    flatpak/platform.bst: Download gtk theme extensions
    
    Currently installing the platform on systems with a non-standard gtk
    theme will not also install the relevant extension, causing theming
    issues. See #105
    
    (cherry picked from commit 69b67953b400f6fac810484c9af6d21962ccdc68)
