Only support Translation-* that are listed in the {In,}Release file

Handle Translation-* files exactly like Packages files (with the
expection that it is ok if a download of them fails). Remove all
"guessing" on apts side. This will elimimnate a bunch of errors
releated to captive portals and similar. Its also more correct
and removes another potential attack vector.
