Make failing webkit_tests fail android build.

Make failing webkit_tests fail android build.

Now that r156332 has landed in theory, the webkit_tests step should pass
(since we're only running one test), and we should start trying to figure
out how reliable the bots actually are.

This change flips the bot config so that a failing webkit_tests step will
cause the build to be red. If this turns out to be premature, I'll revert
this change, but we should start gathering real data on what does and doesn't
work now.

Do you still need 220 - 224?

No, I don't think so, but I'll delete that as a separate change once I take
another look at it (wanted to keep this change minimal).
