selftests/pidfd: adapt to recent changes

Browse Source 
Adapt to changes in commit 9133607de3 ("exit: fix the usage of
delay_group_leader->exit_code in do_notify_parent() and pidfs_exit()").

Even if the thread-group leader exited early and succesfully it's exit
status will only be reported once the whole thread-group has exited and
it will share the exit code of the thread-group. So if the thread-group
was SIGKILLed the thread-group leader will also be reported as having
been SIGKILLed.
