ext/redhat/puppet-dashboard-workers.init: make one worker status work

Make '/etc/init.d/puppet-dashboard-workers status' work in RedHat
environment when there is only one dashboard worker.  The exact issue
is that pid files are numbered when there are multiple of them, but
single worker pid file has no number in it's name.

The fix is similar to Bruno Leon's debian fix from commit in reference.

Changed comment from inline

Apache kept complaining that `AuthUserFile takes 1-2 arguments, text file containing user IDs and passwords`. It took me longer than I'd have like to figure out the inline comment was causing the problem. Hopefully saves another noob some time.
