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 ros-tutorials recipes were updated to 0.3.13 to be in line with
4551e7c32d/hydro/release.yaml.
The previously applied patch has been included in 0.3.13 and is
removed from the recipe and this repository.
