audit: anchor all pid references in the initial pid namespace
Store and log all PIDs with reference to the initial PID namespace and use the access functions task_pid_nr() and task_tgid_nr() for task->pid and task->tgid. Cc: "Eric W. Biederman" <ebiederm@xmission.com> (informed by ebiederman's c776b5d2) Signed-off-by: Richard Guy Briggs <rgb@redhat.com>
