Simplify SVGPathByteStream-based path-query functions

The functions getSVGPathSegAtLengthFromSVGPathByteStream,
getTotalLengthOfSVGPathByteStream and getPointAtLengthOfSVGPathByteStream
all returns a bool that their (single) caller does not look at.
Convert to just return the computed value instead.
