not working in the envoy

[FeiYing9]

due to the issue, I managed to build it with tinygo 0.17.0, and it's succeed.

build command:

tinygo build -o build/socket.wasm -target=wasi -wasm-abi=generic -cflags "-DUNISOCKETS_WITH_CUSTOM_ARPA_INET" .

but, it's failed running in Istio with the proxy of envoy:
