Avoid LSan false positives from CSSPathValue::emptyValue().
LSan reports a leak on SVGComputedStyleTest.MiscStyleShouldCompareValue
(with Oilpan), stemming from emptyValue()'s allocation of an
SVGPathByteStream object. Introduce a local constructor function that
explicitly keeps this sub-object from LSan's view -- it is owned by
the emptyValue singleton and shouldn't be considered a leak.
