Add missing run depends for [robot|joint]_state_publisher

[davetcoleman]

In moveit/moveit#214 I switched our CI to build off of ros-base instead of ros-desktop-full. This means many ROS packages are not installed by default, which uncovered missing dependencies in the python move_group test causing travis to fail:

FAILURE: Test Fixture Nodes ['joint_state_publisher', 'robot_state_publisher'] failed to launch
  File "/usr/lib/python2.7/unittest/case.py", line 329, in run
    testMethod()
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/rostest/runner.py", line 121, in fn
    self.assert_(not failed, "Test Fixture Nodes %s failed to launch"%failed)
  File "/usr/lib/python2.7/unittest/case.py", line 422, in assertTrue
    raise self.failureException(msg)

Should fix moveit/moveit#209

This raised a rosdep error. Please have a look

that looks like an error with rosdep / ros servers. i just retriggered the build, on my local kinetic docker ros-kinetic-robot-state-publisher installed fine...

I found the fix: moveit/moveit#218
