[SVG] Fix SVGPathBuilder subpath point tracking

http://crrev.com/1623073003 introduced a bug where moveTos only update
the subpath point when immediately following a closePath.

This is incorrect: moveTos should always update the subpath point.

Also changed the initial value to PathSegUnknown, since we no longer
