Save one fcntl() syscall on every request

MRI 1.8 always sets O_NONBLOCK on sockets to implement green
threads correctly in the face of slow network I/O.  Since we
already know what the I/O flags for a client socket should be,
we just set it to that instead.

Applications running on Unicorn continue to be green thread-safe
when used fast local traffic.  Of course, Unicorn itself will
never use threads.
