rustix: missing declaration of CWD

[nielx]

When building Rust 1.73.0 + Cargo 0.74.0:

error[E0432]: unresolved import `rustix::fs::CWD`
  --> /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/tempfile-3.7.0/src/file/imp/unix.rs:17:55

   |                                                       ^^^ no `CWD` in `fs`

   Compiling thiserror-impl v1.0.44

src/tools/cargo/Cargo.lock is pinning tempfile at 3.7.0, depending on rustix 0.38.6.

There is some chatter about this issue in bytecodealliance/rustix#478, though have not verified it myself.

Looks like bumping tempfile to 3.7.1 should work: Stebalien/tempfile@bf8f7ea
