Patch to add CATKIN_PREFIX_PATH support to _setup_util.py.in

The standard ROS environment hooks are not run when sourcing devel.{bash,zsh} in a local catkin workspace. This results in environment variables not being set to expected values and tools like roslaunch being unable to find some files in the workspace.

Steps to reproduce (you can't have dev-ros/rospy_tutorials installed):

mkdir -p ~/catkin_ws/src
cd ~/catkin_ws/src
catkin_init_workspace
git clone https://github.com/ros/ros_tutorials.git
cd ..
catkin_make
source devel/setup.zsh
roslaunch rospy_tutorials talker_listener.launch

Expected:

[...]
SUMMARY
========

PARAMETERS
 * /rosdistro: kinetic
 * /rosversion: 1.12.2

NODES
  /
    listener (rospy_tutorials/listener.py)
    talker (rospy_tutorials/talker.py)

auto-starting new master

[...]

Actual:

[talker_listener.launch] is neither a launch file in package [rospy_tutorials] nor is [rospy_tutorials] a launch file name
The traceback for the exception was written to the log file

Reason:

More CMAKE_PREFIX_PATH silliness from Catkin, this time in _setup_util.py. The attached patch is one way to fix this for Gentoo.
