Add a new filter test that got recently activated to known failures list in LBSE (svg/filters/feDisplacementMap-filterUnits.svg), update a bunch of test results that got changed because of other upstream changes (e.g. color serialization) or tests that I forgot to rebaseline after activating subpixel support for LBSE render tree dumps.
