The system test information array now has the full path to the MaxScale
configuration file. The array now only contains labels given in
CMakeLists.txt. The resulting .cc-file has linebreaks for readability.
See script directory for method. The script to run in the top level
MaxScale directory is called maxscale-uncrustify.sh, which uses
another script, list-src, from the same directory (so you need to set
your PATH). The uncrustify version was 0.66.
