fileselector: fix typo + behavior

- _anchors_do() receive fileselector object as first parameter,
    in _on_text_unfocused cb fileselector passed as 'data' and not as
    'obj';
 - when entry is unfocused, it can contain usual text or anchor-styled text,
   so the only secure way to pass path is to pass sd->path.
