    Bug 26362: Use old MAR format for update file creation
    
    Mozilla switched from Bzip2 to LZMA as compression algorithm for MAR
    files during th Firefox 56. That means esr52-based Tor Browsers don't
    understand LZMA yet. Thus, we still use Bzip2 for the first esr60-based
    MAR files and switch afterwards to LZMA.
