utils: don't create pipes non-blocking

Browse source 
The daemonizing code depends on its pipe io being
blocking.  The other user of ply_open_unidirectional_pipe
will work with blocking or non blocking io.

This commit changes ply_open_unidirectional_pipe to create
blocking pipes.  This started causing failures with
commit 9ec69929 since it replaced broken code (passing
O_NONBLOCK to fcntl(fd, F_SETFD.. instead of F_SETFL)
with working code.
