    Bug 31491: clean up the old meek http helper browser profiles
    
    On macOS, remove the old meek and moat http helper browser profiles
    that may be present under TorBrowser-Data/Tor/PluggableTransports/.
    Removal is only attempted once; this is controlled by the Boolean pref
    extensions.torlauncher.should_remove_meek_helper_profiles.
