service worker: Enable 'claim-with-redirect' WPT test.

The test was disabled because Chrome didn't implement updateViaCache and
the expected default behavior, but that has been enabled as an
experimental feature for a while.

Also, delete the corresponding version in http/tests, which used
cache-control headers to workaround the lack of updateViaCache/expected
behavior.
