    backport-autocleanups: Hide autocleanups for types we don't have
    
    If you're building on a really old GLib, you might not have GTask,
    GSubprocess or g_markup_parse_context_unref(), among others. This gets
    libglnx compiling (and apparently working) on GLib versions as old
    as 2.32.
