move g-code quick ref from linuxcnc-uspace to doc debs

The new translation infrastructure means we need to build the translated
docs to generate the g-code quick refs.

Since we have separate "-arch" and "-indep" targets in debian/rules now,
we don't build the docs when building linuxcnc-uspace, so the g-code
refs need to move to the doc debs.
