SNICombinedWithALPNTestCase fails with IBM JDK

SNICombinedWithALPNTestCase added with WFCORE-3873 does not conform with IBM JDK key algorithm name. This needs to be fixed.

Also as IBM JDK 8 and lower does not contain ALPN implementation and neither the ALPN-hack work there (it works only with Oracle JDK and Open JDK as it depends on JDK internals) we would have to provide ALPN in such situation somehow. We can either use Jetty ALPN implementation or wildfly-openssl using OpenSSL libraries. Both variants would bring unwanted difficulties with running this testsuite in our environment.

Let's skip these tests for IBM JDK less than version 9. With newer IBM JDK version, there will probably be ALPN already part of JDK, so we can execute it then.
