Pass the WebSockets test suite.

[Ms2ger]

Tests are under tests/wpt/web-platform-tests/websockets, and expected failures are under tests/wpt/metadata/websockets/. See tests/wpt/README.md for more information on web platform tests.

@jdm What's the best way to get started finding more websockets tests to fix. Should I just look for anything with "expected: FAIL" under tests/wpt/web-platform-tests/websockets ?

All the existing websockets tickets are already being worked on https://github.com/servo/servo/issues?utf8=%E2%9C%93&q=is%3Aissue+is%3Aopen+websockets

@Chandler Yes, we don't necessarily have issues for every failing test, so it's perfectly ok for you to submit a PR and fix them!

@Chandler: FYI, a dump of all the current failures (not including what you fixed in #9367): https://gist.github.com/jsanders/4a348d15aa27067d2b02

There is still a ton of failing tests, notably since we disabled support of wss.
