[gtk-osx] Restore readline to gtk-osx-bootstrap.modules.

[John Ralls <jralls src gnome org>]

commit 14d3d5c6300ac18adecc3afa11cb92c5054a52ad

    Restore readline to gtk-osx-bootstrap.modules.
    
    It's still in bootstrap.modules too, but the Python modules depend
    on it and if the user is on pre-El Cap and skips bash then readline
    won't be installed and building Python will fail.
