Bug#1088076: [debian-mysql] Bug#1088076: galera-arbitrator-4: The -w/WORK_DIR feature doesn't work because of a missing comma in the configuration code

Hi!

Thanks for investigating! If you have a fix, submit it targeting
debian/latest.

If all reviewers agree and it is merged, I can later cherry-pick it on the
other branches. You don't need and should not send the same thing for
multiple branches.
