Revert of Gardening: virtual/softwarecompositing/repaint/resize-repaint.html needs manual rebaseline (https://codereview.chromium.org/393683003/)

Reason for revert:
The test is now passing. And also we seem not to have a way to rebaseline a test for Debug only.

Original issue's description:
> Gardening: virtual/softwarecompositing/repaint/resize-repaint.html needs manual rebaseline
> 
> [ NeedsRebaseline ] was added in https://codereview.chromium.org/371973004, then
> removed in https://codereview.chromium.org/389393004 because rebaseline didn't work.
> But the test is red on Linux Debug, so it needs some rebaseline.
> 
> I also tried using webkit-patch rebaseline-expectations and it didn't create a
> new expectation.
