(test-hironx-ros-bridge.test) Add omniNames script to start it on ros buildfarm (see https://github.com/start-jsk/rtmros_common/issues/416#issuecomment-46846623)

[pre-release test on ros buildfarm (using devel) is failing](http://jenkins.ros.org/job/prerelease-hydro-rtmros_hironx/ARCH_PARAM=amd64,UBUNTU_PARAM=precise,label=prerelease/6/consoleFull) and missing omniNames script in one of `.test` files should be one reason. 

Another possible cause may lie here (below); this doesn't happen on my local machine. But I want to see if this still happens after this PReq is merged:
