lint-man.mk: lint-man-groff-eqn: Fix error detection
eqn(1) could theoretically write _only_ newlines to standard error.
That's unlikely, but I'm still worried that someone (even me) might copy
this trick around, and use it in situations where that might actually
happen. Let's be more precise, and fail when there's literally anything
on standard error.
