Restore compatibiltiy testing against OpenSSL for
(D)TLS versions smaller that 1.2.
. Fix the check for support in OpenSSL for these versions
. For test cases for (D)TLS version smaller than 1.2,
restore the configuration of OpenSSL client/server
with the given TLS version, as it was before #5660
that broke it.
