fix: hurd build, stat64.st_fsid was renamed to st_dev

On hurd, `stat64.st_fsid` was renamed to `st_dev` in https://github.com/rust-lang/libc/pull/3785, so if you have a new libc with this patch included, and you build std from source, you get this error:

```sh
error[E0609]: no field `st_fsid` on type `&stat64`
   --> /home/runner/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/library/std/src/os/hurd/fs.rs:301:36

    |                                    ^^^^^^^ unknown field
    |
help: a field with a similar name exists
    |
