mbn: Updated file parsing to newer file version to suppresss warning

Note: the parsed data is not actually used. The personalization just
involves replacing the last N bytes of the file with the blob data
(of size N) returned by the signing server. However this at least
suppresses a warning message and helps identifying newer format versions.
