GEODE-1198 CI Failure: DistributedSystemDUnitTest.testConflictingUDPPort

Reinstate expectation that SystemConnectException may be thrown when
connecting the second node to the system.  The first node will have grabbed
one UDP port from the membership-port-range but if there isn't another
port free in that range the second node will throw SystemConnectException
instead of GemFireConfigException.
