Wrong catch_ros include dir in certain situations

[xqms]

As discovered in AIS-Bonn/catch_ros#15, we currently prefer the catch_ros headers from e.g. /opt/ros/noetic/include in favor of the (correct) ones from the current workspace.

The reason is this line:

nimbro_network/nimbro_topic_transport/CMakeLists.txt

Line 170 in 7e1de20

include_directories(${catch_ros_INCLUDE_DIRS})

... which adds the catch_ros headers to the end. Instead, we should use catkin's list_insert_in_workspace_order() function to correctly insert the additional include path.
