QAbstractFileEngine: add a path parameter to beginEntryList()

Change beginEntryList() to take a path parameter, which it passes on
to the QAFEIterator constructor; setting the path at construction
makes more sense, because typically the path isn't supposed to change
during iteration, and this simplifies the code at the call site.

Remove setPath(), the last usage in Qt repos was in QtCreator, and that
has been ported away from it.
