catkin tests: Catkin test results directory collides in devel space

[jbohren]

The 05.catkin-test-results.sh file is over-written by all packages built in a merged devel space. Each one of them puts a path to it's own build directory in that file.

Fixing this might require adding a CATKIN_TEST_RESULTS_DESTINATION CMake variable which catkin_tools can set so that test results go to the right place.

@dirk-thomas Does that look like a fair assessment?

Might be related to #139

[dirk-thomas]

The CATKIN_TEST_RESULTS_DESTINATION environment variable will be gone in the upcoming catkin version. See ros/catkin#719 for details.

[jbohren]

Ah cool. Will that be released into the hydro version of catkin?

[dirk-thomas]

I don't think the change will be backported to Hydro. Hydro will be EOL in about a month. I don't think it is a good idea to change it anymore.
