Fix broken build for ESP IDF due to #119026

`target_os = "espidf"` in `libc` lacks the `SOMAXCONN` constant, but that's probably irrelevant in this context, as `UnixListener` is not supported on ESP IDF - it being a single process "OS" only.

The PR just re-uses the `128` constant so that the code builds. Trying to use the listener on ESP IDF will fail with `ENOSYS`, which is fine.

*UPDATE* Might not fail with `ENOSYS` - need to test what error code would be returned, but that doesn`t change anything.
