test: fix renegotiation tests in pummel
With a recent OpenSSL update to core, a change in the behavior of
s_client
result in pummel test failures because they spam with
renegotiation requests before the renegotiation is complete. Modify
tests to reduce initial spamming.
This fixes the TLS renegotiation test. While it fixes the bug in the HTTPS test too, that is still failing with the OpenSSL update for other (too-be-determined) reasons.
