libarchive: sanitize non-UTF8 archive entries

Some client API users simply don't like such filenames. For their sake,
don't return them, but return a dummy filename instead. (Returning a
latin1-ized version would work too, but is slightly more work.)

Also remove the "\n" from the replacement dummy filename. This was
accidental.
