Unrolled build for rust-lang#133515

Rollup merge of rust-lang#133515 - SteveLauC:fix/hurd, r=ChrisDenton

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

On hurd, `stat64.st_fsid` was renamed to `st_dev` in rust-lang/libc#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
