REGTESTS: ssl: Fix ssl_errors regtest with OpenSSL 1.0.2

This test was broken with OpenSSL 1.0.2 after commit a996763619d
(BUG/MINOR: ssl: Store client SNI in SSL context in case of ClientHello
error) because it expected the default TLS version to be 1.3 in some
cases (when it can't be the case with OpenSSL 1.0.2).
