Fix pasto for this is OpenBSD, not FreeBSD

@andrewkroh is this the box I prepared? If so, the comment marker is slightly off for it's really 5.9-current instead of 5.9 ;-) I can amend this PR accordingly if you like.

Jenkins standing by to test this. If you aren't a maintainer, you can ignore this comment. Someone with commit access, please review this and clear it for Jenkins to run; then say 'jenkins, test it'.

It's based on an image hosted on Atlas built from this packer template. Here's a copy of the Vagrantfile and provisioning script. https://gist.github.com/andrewkroh/b6d7dbf691db2ffd78df115ffb3a12fa

It's not based on yours because I didn't want to source control the original image, but if you post an updated image to Atlas after your openbsd pcap PR merges, then I'll update it again.

Thanks for fixing the copy/paste problem.

Great, I'll be sure to push an image to Atlas and let you know.
