Fix CI failures: cross-platform regressions

- winapi.rs: pass None to create_event_w; the recent Option<&WideCStr> migration left one call site still passing a raw null pointer. - exceptions.rs: gate ToPyException for LockfError with cfg(any(unix, target_os = "wasi")), matching host_env::fcntl's own cfg. The previous cfg let it compile on wasm32-unknown-unknown where host_env::fcntl does not exist. - io_unsupported.rs: derive Eq on FileMode alongside PartialEq to satisfy clippy::derive_partial_eq_without_eq.
