Problem description

When running tlsfuzzer within NSS upstream CI, the following test gets timeout:

test-tls13-version-negotiation.py:stdout:SSL 2.0 ClientHello with TLS 1.3 version and TLS 1.3 only ciphersuites ...
test-tls13-version-negotiation.py:stdout:Error encountered while processing node <tlsfuzzer.expect.ExpectAlert object at 0x7f00e9857b50> (child: None) with last message being: None
test-tls13-version-negotiation.py:stdout:Error while processing
test-tls13-version-negotiation.py:stdout:Traceback (most recent call last):
test-tls13-version-negotiation.py:stdout:  File "scripts/test-tls13-version-negotiation.py", line 435, in main

test-tls13-version-negotiation.py:stdout:    "Timeout when waiting for peer message")
test-tls13-version-negotiation.py:stdout:AssertionError: Timeout when waiting for peer message

Describe how to reproduce the problem

1. apply the patch from the phabricator to nss trunk
2. build nss
3. modify the tlslite-ng commit ID in tests/tlsfuzzer/tlsfuzzer.sh
4. run the tests

Expected behaviour

The test receives the appropriate alert (decode_error).

this is related to SSLv2 removal, so we need to create a SSLv2 Hello that is a clearly malformed SSLv3 record
