After writing https://github.com/chef/ohai/pull/1841 I THINK I know what the problem is here.

FreeBSD reports no scope for global addresses. Further, it uses scopeIDs, not scopes, so the sorting that happens here doesn't work at all.

So the right fix here is to modify this code to:

1. Convert scopeIds into scope names
2. If no scopeID is there, just set it to 'global' which seems to be what FreeBSD is assuming.

@jaymzh Didn't get time over the weekend, and don't know when I will in the next few weeks, so let's close for now.
