Fix network communication on arm64 - continued

The 55d8b880fca26ccf4b897bca1fe66796b9972345 commit on the original pigpio repo fixed parsing data received from a socket on 64bit systems.
This one fixes also the response that is being sent back to the socket - 64bit array is translated back to a 32bit array that is passed to the send function.
