[fuchsia][webrunner] Add integration / smoke test for webrunner

This adds a black-box test of the webrunner's functionality as a runner for http:// URLs in Fuchsia. The test opens up a random port on the device, instantiates web runner via launching a web URL, then verifies that the URL is fetched and parsed.
