Fix QGtkPainter::reset() to reset the clip rect

Due to preparation for GTK3 support, QGtkStyle::drawXxx() no longer
creates a local instance of QGtkPainter upon every call, but
QGtkStylePrivate::gtkPainter() will (in the future) dynamically choose
between QGtk[2|3]Painter. The same painter instance is now re-used
between the calls, but wasn't properly reseted between.
