PageIndicator: don't block touch when non-interactive

Unlike with mouse events there's setAcceptedMouseButtons(), currently
there's no way to control whether a control receives touch events or
not. As a temporary workaround until QQuickItem::setAcceptTouchEvents()
has been added, we'll have to ignore touch events by hand.
