[TEST_BUG] test/sun/security/ssl/javax/net/ssl/SSLContextVersion.java requires backport to JDK 6

In the scope of TLS1.1 enabling for JDK 7 following JDK-6976117 was fixed.

Besides code changes, regression test was created:
jdk/test/sun/security/ssl/javax/net/ssl/SSLContextVersion.java

In the scope of TLS1.1 backporting to JDK 6, JDK-6976117 was also backported to JDK 6.
(Checked that PIT build didn't contain reported problem.)
However, regression test itself doesn't exist in the JDK 6 workspace.
