signal: During coredumps set SIGNAL_GROUP_EXIT in zap_process
There are only a few places that test SIGNAL_GROUP_EXIT and are not also already testing SIGNAL_GROUP_COREDUMP. This will not affect the callers of signal_group_exit as zap_process also sets group_exit_task so signal_group_exit will continue to return true at the same times. This does not affect wait_task_zombie as the none of the threads wind up in EXIT_ZOMBIE state during a coredump. This does not affect oom_kill.c:__task_will_free_mem as sig->core_state is tested and handled before SIGNAL_GROUP_EXIT is tested for. This does not affect complete_signal as signal->core_state is tested for to ensure the coredump case is handled appropriately.
