[PATCH 6/8] coredump: Stop setting signal->group_exit_task

Eric W. Biederman

Currently the coredump code sets group_exit_task so that
signal_group_exit() will return true during a coredump. Now that the
coredump code always sets SIGNAL_GROUP_EXIT there is no longer a need
to set signal->group_exit_task.
