tst_QSslSocket::oldErrorsOnSocketReuse - make it work with OpenSSL v3

The initial problem was in server not starting encryption, because
its certificate was rejected by OpenSSL (v3) saying 'weak md'.
After the certificate was replaced, we got another problem - due
to the fixed TLS v.1 protocol for both client and server - handshake
is interrupted early with 'tls v1 alert' and error message
saying about not found signature algorithms. Don't fix the protocol
version, use proper QSsl::SecureProtocols (default).

Pick-to: 6.4 6.3 6.2 5.15
