Enable universal newlines in chromium android layout test runner

Enable universal newlines in chromium android layout test runner
https://bugs.webkit.org/show_bug.cgi?id=80418

Patch by Sami Kyostila <skyostil@chromium.org> on 2012-03-06
Reviewed by Adam Barth.

The Chromium Android layout test runner uses the 'adb' program to
communicate with the Android device. Adb uses CRLF ('\r\n') to delimit
output lines from the test runner, while the test expectation files are
written with LF ('\n') delimiters. This causes the results to have
spurious whitespace differences, making them more difficult to
interpret.

The fix is to enable universal newlines for the DumpRenderTree pipe,
causing the output to only contain LF newlines like on other platforms.
