Run the DDSHelloWorld example test.

Runs the DDSHelloWorldPublsher and DDSHelloWorldSubscriber applications in
parallel for 15 seconds. These return an exit code equal to 0 in case of
successful completion, that is, if the publisher sends all the samples and the
subscriber receives all of them. If the timeout occurs, both applications are
forced to end with a return code other than 0.
