release.mk copied server/i18n wholesale into the distribution. Everything in
that directory today is a catalog, so it made no difference -- but the server
loader, mmgotool and the sync test all already filter the directory to *.json,
and packaging was the one consumer that did not.
Copy the catalogs explicitly so documentation and any other non-catalog file
placed alongside them stays out of the release bundle.
