SSLEngineTest: set up server instead of using anon

This test was relying on "anon" cipher suites so that it didn't have to
do any complicated setup of the server certificate store. Fortunately we
already have a utility class we can use that does this setup for us so
there is no need to rely on anonymous cipher suites that do no
authentication.
