Fix wallpaper window can't receive up event

If the wallpaper window is touchable and the above touched window has
`DUPLICATE_TOUCH_TO_WALLPAPER` flag, it would also deliver the same
touch event to the wallpaper window, and it have to set the
corresponding pointer ids to prevent it being erased in next pointer up.
