Subject: [PATCH] use statfs64 on apple, while retaining statfs on freebsd

http://git-annex.branchable.com/bugs/Makefile_is_missing_dependancies/#comment-3196b43b7d745ab206435d0a69686815
indicates statfs64 works on apple. Probably on freebsd too, but I
have not tested it and so will stick with the old code there.
