Never parse Version/Architecture tags in a Translation-$lang file

Version/Architecture information in a Translation-$lang file is
not allowed, so don't try to parse it. This is a fix for a bugreport
where a Translation-en file contained the content of the regular
Packages file (probably due to local FS corruption). This lead to
strange error messages on file download.

Thanks to Thomas Reusch for the report.
