Cygwin: FIFO: add support for the duplex case

If a FIFO is opened with O_RDWR access, create the pipe with
read/write access, and make the first client have the handle of that
pipe as its I/O handle.

Adjust fhandler_fifo::raw_read to account for the result of trying to
read from that client if there's no data.
