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.
The test unnecessarily did an unconditional drop of the user resulting in
errors. Also prevented stopping of MaxScale if it wasn't started in the
first place.
