Cygwin: re-implement fhandler_fifo::open with O_PATH

Browse Source 
If the O_PATH flag is set, fhandler_fifo::open now simply calls
fhandler_base::open_fs.

The previous attempt to handle O_PATH in commit aa55d22c, "Cygwin:
honor the O_PATH flag when opening a FIFO", fixed a hang but otherwise
didn't do anything useful.
