Function `sem_init` is not found on Redox with `v3.5.0`

Hi,

I noticed in our CI that the new release, 3.5.0, fails on Redox with the following error:

Compiling ctrlc v3.5.0
error[E0425]: cannot find function `sem_init` in crate `nix::libc`
    --> /home/runner/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/ctrlc-3.5.0/src/platform/unix/mod.rs:19:20

     |                    ^^^^^^^^ help: a function with a similar name exists: `res_init`

Oh boy, I made the mistake of merging in new code and this is where we end up again. I guess there's still a need for the pipe based solution for systems that don't have full POSIX compatibility.

Any progress for this?

No. 3.4.x works for a workaround. I am open for contributions but I'm not planning on implementing this myself any time soon.
