Title: fix env.sh for plain cmake packages to not define _CATKIN_SETUP_DIR

This was breaking isolated builds by not passing along the environment of the packages *before* the plain CMake package. By setting `_CATKIN_SETUP_DIR` in the plain CMake env.sh it breaks the parent setup.sh since there is no _setup_util.py in that folder.

@wjwwood Please review.
