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 native packages are not required anymore, because the needed
python scripts during compile time are also provided by the
cross-compiled packages and the python scripts are platform
independent. Only the catkin package is provided as native package.
The recipes are supposed to cross-compile and install the chatter
example. In this commit, the recipe do not contain any dependencies
and configure does not run through yet.
