test: fix test-tls-junk-closes-server

Refs: #53382

TLS spec seems to indicate there should should be a response
sent when TLS handshake fails. See
https://datatracker.ietf.org/doc/html/rfc8446#page-85

When compiled with OpenSSL32 we see the
the following response '15 03 03 00 02 02 16' which
decodes as a fatal (0x02) TLS error alert number 22 (0x16).
which corresponds to TLS1_AD_RECORD_OVERFLOW which matches
the error we see if NODE_DEBUG is turned on once you get
through the define aliases.

If there is a response from the server the test used to
hang because the end event will not be emitted until after
the response is consumed. This PR fixes the test so
it consumes the response.

Some earlier OpenSSL versions did not seem to send a response but
the error handling seems to have been re-written/improved
in OpenSSL32.
