[compiler-rt] Fix endianness in get_sock_peer_name test

[mgorny]

Summary

Fix passing the port and IP address with the wrong endianness
in get_sock_peer_name() that causes the connect() to fail inside
without an outgoing network interface (it's trying to connect
to 1.0.0.127 instead of 127.0.0.1).

@vitalybuka, I suspect this might also fix the test on Android but I don't have an environment to test it.

Thanks for the prompt review!
