Make PathChooser always use QPushButtons

It might look a little bigger, but since we are using
QPushButtons by default in the options pages it's more
uniform considering the buttons around.

If we "conclude" it looks weird or unpleasant in other
places (like in the wizards, for example) we can consider
an alternative approach.
