fmemopen.3: Remove bogus suggestion to use setbuffer()
As Rich Felker comments:
The stdio buffer associated with the fmemopen-obtained FILE,
and the output memory buffer into which it's writing, are
conceptually distinct entities, and there is no reason to
expect reasonable results if you modify the contents of a
setvbuf-associated buffer through other means while it's
associated with a FILE.
