setterm: Document behavior of redirection

Debugging an error of setterm, I realized that setterm --powerdown operates
on stdout but setterm --powersave operates on stdin. Such unexpected
behavior should be documented.

I prefer a less accurate generic "always redirect both stdin and stdout"
over recommending of the correct I/O stream for each option separately.
