Andrey Vagin ef3ca3a104 restore: do not kill processes if not-all of them have been created 
If processes are restored without pidns, criu knows pidtheir -s from images,
but part of those task may have not yet forked, and thus the pids can not
exist or (!) be used by other processes.

To address that we abort stages RESTORE_NS and FORKING without killing tasks,
but with task_entries->start futex by writing STATE_FAIL into it and making
the tasks to check that. Since during RESTORE_NS and FORKING stages tasks can
only block on the mentioned futes, we can safely do it.
