libfetch: Use select(2) as a consequence of switching to non-blocking
Since the socket is non-blocking, it is necessary to use select(2) even
when there is no timeout, because read(2) will return immediately if there
is no data waiting in the TCP buffer, causing fetch_read() to busy-loop on
slow connections.
