[ Win7 Oilpan ] emphasis-combined-text and emphasis-vertical tests fail

Oilpan is enabled on ToT, and is reading from TestExpectations and has
no Expectations file of its own (for now).

Mark the tests as a flake, and place them in TestExpectations "Oilpan"
area of that file.  They fail both in Oilpan Win Release and Debug.

issue 521730.
