Make getPutImageDataPairTest.html pass

There are two reasons for this CL:
1. This layout test times out on virtual/gpu/ test suite.
2. The layout test is uses testharness, but it has an expected file.

The reason for #1 is that when the test creates a canvas, it uses the
canvas's default width and height which is 300*150, and call getImageData
and putImageData on the entire canvas with the same color. We really don't
need that, this CL sets the width and height to be 5 and should test the
same thing.

The reason for #2 is that this layout test has several small tests, the
name for each small tests are the same, and testharness apparently
doesn't like that.

This CL removes a line in the expectation file, and some -expected.txt
