Upgrade Jetty and make test server listen only on localhost. (issue 258980043 by kpreid@google.com)

[re...@codereview-hr.appspotmail.com]

Reviewers: felix8a,

Description:
Fixes half of <https://github.com/google/caja/issues/1964>, test server
being visible to the network.

The Jetty upgrade is needed because the ancient Jetty version we had
did not allow binding to an address. We are upgrading to Jetty 8, not
Jetty 9, so as to not require Java 8.
