tdf#115671 vcl opengl: fix drawing of polylines with duplicate points
The bugdoc had a custom shape, the interesting part of it was a triangle
with miter line join, where the last segment was missing. In that case
RenderList::addDrawPolyLine() mishandled the polyline, as it does not
expect duplicate points in it.
