modgo-gen-modules-helper: print MODGO_VERSION to STDERR

ports@,

Here a small patch for modgo-gen-modules-helper which redirects output of
MODGO_VERSION into STDERR. The goal is avoid editing modules.inc by removing
that variable from this files by maintaners of go-prot then they do:

make modgo-gen-modules > modules.inc

Locally, I enjoy it for last week.

Feedback? Ok?
