While on Windows guests that's all we can get with GetDiskFreeSpaceExA(), on POSIX guests we might also be interested in total file system size, as it's visible for root user. Let's add an optional field 'total-bytes-privileged' to GuestFilesystemInfo struct, which'd only be reported on POSIX and represent f_blocks value as returned by statvfs(3). While here, also tweak the docs to reflect better where those values come from.
