A bit more fairness into the signal interruption of fifo open
The patch would prefer to return success over the EINTR when signal is
delivered while other end of fifo becomes ready simultaneously.
Note that the patch still does not fix the fundamental underground issue of the
troubles, which is in the test structure itself. If child reader manages to
close fifo before the parent writer sleeping in open has a chance to run,
parent would deadlock, since nothing else would open the fifo for read.
