[gtk/builtin-icontheme-fix-for-4-6] Add more directories to the builtin hicolor index

[Matthias Clasen <matthiasc src gnome org>]

    Add more directories to the builtin hicolor index
    
    We haven't had any scalable directories in this list.
    Add some. Since we seem to have settled on including
    just actions and status as subdirectories for each
    size, add scalable/actions and scalable/status.
    
    Fixes: #4960
