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 recipe are updated to 0.4.1 to be in line with
https://github.com/ros/rosdistro/blob/bb9ffa139d8f1b251cca3c29c458c19ccb25e5d1/hydro/release.yaml.

The ros-tutorials recipes were updated to 0.3.13 to be in line with
https://github.com/ros/rosdistro/blob/4551e7c32d1b34984410b79bc0ec36afe3d3d245/hydro/release.yaml.
The previously applied patch has been included in 0.3.13 and is
removed from the recipe and this repository.
