[wip/genom3] Add a dependency on ros-rospack for ros-* options

genom3-ros components and clients indirectly use rospack to generate
messages. Since the debian packages don't have an RPATH, it is important to
register the dependency so that robotpkg exports the proper LD_LIBRARY_PATH.

This fixes the build of wip/demo-genom3 with a system ros-fuerte.
