Increase repaint test delay when running in browser

Increase repaint test delay when running in browser

When running a repaint test in browser, sometimes we may want to see
the page contents before and after repaintTest(). The origianl 100ms
delay seems too short to show the page contents before repaintTest().

This may be more useful when we have repaint overlay feature when
showing layout test results (https://codereview.chromium.org/303223008/).

That seems like a fairly large timeout increase. How many tests use this? Does
this noticeably affect cycle time?

The timeout is only used when running the tests manually in browser, not used
during real layout tests :)

Ah, right. Sorry I didn't read more closely. 

LGTM.
