pefile: Fix the failure of calculation for digest
Commit e68503bd68 forgot to set digest_len and thus cause the following
error reported by kexec when launching a crash kernel:
kexec_file_load failed: Bad message
Fixes: e68503bd68 (KEYS: Generalise system_verify_data() to provide access to internal content)
