test: remove potential race condition in https renegotiation test
In test/pummel/test-https-ci-reneg-attack.js, there is a boolean that is set by the server and checked by the client, which is a separate process launched with child_process.spawn(). The boolean is not actually required by the client and might even be causing a race condition on some operating systems. Remove it.
