Rollup merge of #82500 - CDirkx:hermit-pipe, r=joshtriplett

Reuse `std::sys::unsupported::pipe` on `hermit`

Pipes are not supported on `hermit` and `hermit/pipe.rs` is identical to `unsupported/pipe.rs`. This PR reduces duplication between the two by doing the following on `hermit`:

```rust
#[path = "../unsupported/pipe.rs"]
pub mod pipe;
```
