Make pipe() return a set of bidirectional pipe fd's rather than one-way only
just like on SVR4.
This has no effect on any current programs in our source, but makes
the use of SVR4 code a little easier. There is no code or implementation
cost in the kernel.. This two-line change merely sets the modes on the ends
of the pipes to be bidirectional. There are no other changes.
