REGTESTS: workaround for a crash with recent libressl on http-reuse sni

Disable the ssl-reuse for the sni test on http_reuse_conn_hash vtc. This
seems to be the origin of a crash with libressl environment from 3.2.2
up to 3.3.1 included.

For now, it is not determined if the root cause is in haproxy or
libressl.

Please look for the github issue #1115 for all the details.
