openssl: pull test case from upstream commit 62af0446569a

The test case added by r60310 ("fix OpenSSL::SSL::SSLContext#min_version
doesn't work", 2017-10-21) does not pass with OpenSSL >= 1.1.0 or
LibreSSL >= 2.6.0. Check that the default 'min_version' value is
properly enforced by actually attempting a handshake rather than by
inspecting the SSL option flags.  [ruby-core:83479] [Bug #14039]
