Mac/CG pixel results on Lion vary if the display color space is changed.

The attached patch will fix this by returning to our old behavior of setting the systemwide color profile. However, it will address the two concerns from https://bugs.webkit.org/show_bug.cgi?id=72424 by using the new (to us) LayoutTestHelper hooks in run-webkit-tests.

With this patch applied, pixel results from WkTR and DRT match both between each other, and between any chosen system color space.

We should probably find a way to share LayoutTestHelper source with the Chromium port (they're still using deprecated ColorSync API in order to support Leopard), though I'm not sure where to put the code if we do. We'll have to work that out.
