Enable FPDFAnnotEmbedderTest.RenderMultilineMarkupAnnotWithoutAP for Skia.

When rendering annotation_markup_multiline_no_ap.pdf, Skia's rendering
result is different from AGG's due to Skia and AGG handle anti-aliasing
on drawing paths differently. Once anti-aliasing is turned off, Skia and
AGG have almost the same rendering results (At scale 1, Skia is more
consistent on rendering the wavy underlines. And at larger scale, Skia's
result matches AGG's perfectly.).

Since skia's rendering result for this embedder test is acceptable, this
CL adds the expected result for Skia so that this test can be enabled.
