[gtk+/gtk-2-24] filechooserentry: Simplify code

    filechooserentry: Simplify code
    
    Use all the clever functions we invented in recent refactorings to
    compute the file and dir part and the current folder.
    
    This also fixes the bug where "./" was not taken as the current
    directory but interpreted as a file named "./".
