fix kabi breakage due to exec is_check 

hulk inclusion
category: feature
bugzilla: https://gitee.com/openeuler/kernel/issues/IAZ996


CVE: NA

----------------------------------------------------------------------

Since struct audit_context and linux_binprm contains hole at the end, we
can directly add one list without breaking KABI.
