When CATKIN_ENABLE_TESTING is deactivated, the ROS packages do not
require the rostest package.
This commit includes a number of patches to be submitted in the
upstream repositories and removes the rostest dependencies from
the recipes.

The tf recipe is updated to 1.10.6 to be in line with
https://github.com/ros/rosdistro/blob/9cb0c7fb0565614f2b5482a8a6c9411ad7bf257c/hydro/release.yaml.

The previously applied patch is incorporated in the hydro release
version of the tf package. Also, the new tf package has further
dependencies.
