avoid degenerate point in addPath extend mode
SkPath::addPath(... SkPath::kExtend_AddPathMode) duplicates
the last point if the added path first point is the same,
resulting in:
path.xVerbTo(..., pt);
path.lineTo(pt);
The extra point has no effect in filling or stroking.
Pathops uses extend mode a lot; fixing this avoids
the output of Op() and Simplify() requiring another pass
through Simplify() to reduce the path to its minimum.
