fanotify: allow reporting pidfds for reaped tasks
Fanotify used to refuse to report pidfds for reaped tasks by applying a
pid_has_task() check before calling pidfd_prepare(). This prevented
userspace from obtaining information about the task.
Register the event pid with pidfs when creating the fanotify event if
pidfd reporting was requested, so pidfd_prepare() can later create a
pidfd for the reaped task.
