As for other Audit's "pid" fields, Landlock should use the task's TGID instead of its TID. Fix this issue by keeping a reference to the TGID of the domain creator. Existing tests already check for the PID but only with the thread group leader, so always the TGID. A following patch adds dedicated tests for non-leader thread. Remove the current_real_cred() check which does not make sense because we only reference a struct pid, whereas a previous version did reference a struct cred instead.
