[PATCH 01/23] pipe.7: also mention writev(2) in atomicity section

From: наб <redacted>

writev(2) notes that buffers don't interleave with other process'
(a reasonable question to ask), but points to pipe(7) for an exception.
pipe(7) did /not/ mention "writev", "iov", "scat", or "gath", which are,
in order, reasonable search terms: this was confusing at best and
alarming at worst

By mentioning writev(2) in the heading, we clearly note that this sort
of interleaving behaviour matches write(2)'s and isn't a concern
