Whelp, that's bizarre: AFAICT that file type has never been used by any of the mainline BSDs.
I guess you could have had a bitflip from a bug (or drive issue, or cosmic ray, etc) and it should really be either 0120000 (symlink) or 0140000 (socket). You could try tracking it down (update dump to print the inum too?) and then use find(1) to see what path(s) it has to get a hint about what it should have been, and then maybe use fsdb to change its type to what seems the correct one, though I would *test* my backup before doing that and be prepared to spend the time to newfs+restore the filesystem in case things go wrong.
