Drools-apps CSIT randomly fails deploying policies

The drools-apps CSIT was randomly failing while deploying policies
to xacml-pdp.  The message that xacml-pdp published only contained
the naming policy, thus the test failed.

The supposition is that the topic monitoring script returned an earlier
message from when the xacml-pdp first started up.  Modified the robot
script to be more specific when searching for the deployment message.
