elementary: fix legacy path set/get for Fileselector specializations

Fix legacy functions elm_fileselector_path_get and
elm_fileselector_path_set.
Make these functions call the correct function when called with a
specialization of Elm.Fileselector (instead of the base class function).

Create internal versions of path set/get functions to avoid warnings
about deprecated function calls.

Fix T4198
