Keep a Redox-specific removal path. posix_unix_like is selected for Redox, and os::rmdir reaches remove_dir_at on non-Windows targets. Rustix does not expose fs::unlinkat on Redox, so this call causes the supported Redox build to fail. Retain the Redox-specific implementation or cfg-gate the shared call.

I opened a PR for Rustix to expose some of the missing *at functions for Redox.

@joshuamegnauth54, thanks for the update.
The shared implementation can replace the Redox fallback after this PR updates to a Rustix release that exposes fs::unlinkat for Redox. Until then, the current dependency still needs a Redox-specific path or conditional compilation to keep Redox builds working.

Seems like the humans are having a chat. I'll hop back into my burrow for now. If you need me again, just tag @coderabbitai in a new comment, and I'll come hopping out!

Keep Redox off the rustix unlinkat path
When compiling for target_os = "redox", this reference cannot resolve: the locked rustix 1.1.4 release exposes fs::unlinkat only under #[cfg(not(any(target_os = "espidf", target_os = "redox")))]. Because posix_unix_like is compiled on Redox, the new helper prevents the target from building before the newly advertised rmdir(dir_fd=...) support can be used; retain a Redox-specific fallback or use an API that rustix actually provides there.

Preserve the Redox-specific directory-removal fallback. posix_unix_like.rs is compiled for Redox, but rustix::fs::unlinkat excludes target_os = "redox". The Redox host_env build therefore fails at this call. Keep the Redox fallback or apply a target-specific configuration that avoids this call.
