With this patch, we will make sure that verification check in

The only exception would be
- the case where a digest algorithm used in signature is not supported by
U-Boot, or
- the case where parsing some portion of authenticode has failed

just ignore them.
Please note that, due to this change, efi_signature_verify_with_sigdb()'s
function prototype will be modified, taking "dbx" as well as "db"
instead of outputing a "certificate." If "dbx" is null, the behavior would
