RFR: 9: 8155049: New tests from 8144566 fail with "No expected Server Name Indication"

[Rajan Halade]

Please provide your review of this one line fix.

These tests fail on machine where non-FQDN hostname is returned. As per 
RFC for SNI extension, hostname needs to be fully qualified DNS hostname 
and same is asserted in JDK when it adds hostname to SNI extension. This 
fix skips test execution if hostname returned is not fully qualified.

Thanks,
