Update outdated XHR layout test.

The explanation in the HTML file says the expected Content-Type is
application/xml, but it actually is text/plain. This is correct
according to the XHR spec, and application/xml was legacy WebKit behavior.

The HTML file also references a WebKit bug that specifies the old
behavior, and will be updated to reference a Chromium bug for the
correct behavior.

The test passed before and will still pass after this test. However,
running it manually in the browser will be less confusing.
