message[] field won't be part of the definition of mz header.
This change is crucial for enabling kexec_file_load on arm64 because
arm64's "Image" binary, as in PE format, doesn't have any data for it and
accordingly the following check in pefile_parse_binary() will fail:
chkaddr(cursor, mz->peaddr, sizeof(*pe));
