Enable embedder tests RenderWithPause and RenderWithoutPause for Skia/SkiaPaths.

In test suite FPDFProgressiveRenderEmbedderTest, when Skia/SkiaPaths
is enabled, the rendering results for RenderWithPause and
RenderWithoutPause have acceptable small discrepancies on the edge of
texts, which is caused by Skia uses different anti-aliasing and font
face rendering methods compared to AGG.

This CL updates the Skia/SkiaPaths expected checksums for these two
tests so that they can pass.
