product-details: stop generating devedition l10n files (#1596)

This brings back a check removed by commit 055c149 "product-details:
don't ask hg.mozilla.org for data we already have".  Commit fa95b9c
"product-details: don't skip l10n for devedition entirely" re-added l10n
fetches for devedition, so we again need to skip it in `get_l10n` to
avoid committing these files
(#1588 was filed to
consider whether we want to do something about it longer term).
