common/mlutils: Unix_utils.StatVFS.statvfs: This commit implements a full-featured binding for the statvfs(3) function. We then use this to reimplement the daemon statvfs API in OCaml. Note that the Gnulib fallback is dropped in this commit. It previously referenced non-existent field names in the fs_usage struct so it didn't work. Also it's not necessary as POSIX has supported statvfs(3) since 2001, it's supported in *BSD, macOS > 10.4, and there is already a Windows fallback.
