Remove Skia suppressions.

skia/skia_test_expectations.txt

 # TEMPORARY overrides of
 # src/third_party/WebKit/LayoutTests/platform/chromium/test_expectations.txt
 # that are associated with changes to the Skia code.
 #
 # GUIDELINES:
 # - This file should be empty most of the time.
 # - Expectations should only be added TEMPORARILY, as a step towards
 #   rebaselining layout test results.  If any one expectation remains in here
 #   for more than a week or two, then we are probably doing something wrong.
 # - Expectations from this file should NOT be rolled into any other

 # 5. Commit your DEPS roll CL, and keep an eye on the waterfall bots to make
 # sure nothing goes red.
 #
 # 6. Make sure to rebaseline the layout tests as soon as possible!  The longer
 # we leave overrides in this file, the harder it will be to rebaseline those
 # tests (because other rendering changes might creep in).
