popupMenu: Flip the popup menu triangle for RTL

Triangles should be flipped in RTL. This is the easiest way to do it that
doesn't rely on modifying the rotating logic, though it is a bit hacky since
the ClutterActor "scale-x" property technically considers the lower bound
to be 0. It works, though.
