Change to default value of FIPSOperationMode in tm1s.cfg and cogstartup.xml

As of IBM Planning Analytics, the default value of the FIPSOperationMode configuration parameter in tm1s.cfg and cogstartup.xml is FIPSOperationMode=2.

The default value in previous versions of Planning Analytics was FIPSOperationMode=1.

The change to FIPSOperationMode=2 is necessary to enable future security updates to third-party libraries in IBM Global Security Kit (GSKit).
