Support build target `wasm32-unknown-emscripten`

[ChanTsune]

Hi @console-rs members!

I found that #[cfg(unix)] and #[cfg(target_arch = "wasm32")] conflicted when building with wasm32-unknown-emscripten as the target, so I changed #[cfg(unix)] to #[cfg(all(unix, not(target_arch = "wasm32")))] to resolve the conflict.

Current behavior

cargo check --target wasm32-unknown-emscripten

failed on unix
