h8300: Fix build errors from do_exit() to make_task_dead() transition

commit 3957214e14bb80ddfaebca843549f45bae66212b upstream.

When building ARCH=h8300 defconfig:

arch/h8300/kernel/traps.c: In function 'die':
arch/h8300/kernel/traps.c:109:2: error: implicit declaration of function
'make_dead_task' [-Werror=implicit-function-declaration]
  109 |  make_dead_task(SIGSEGV);
      |  ^~~~~~~~~~~~~~

arch/h8300/mm/fault.c: In function 'do_page_fault':
arch/h8300/mm/fault.c:54:2: error: implicit declaration of function
'make_dead_task' [-Werror=implicit-function-declaration]
   54 |  make_dead_task(SIGKILL);
      |  ^~~~~~~~~~~~~~

The function's name is make_task_dead(), change it so there is no more
build error.

Additionally, include linux/sched/task.h in arch/h8300/kernel/traps.c
to avoid the same error because do_exit()'s declaration is in kernel.h
but make_task_dead()'s is in task.h, which is not included in traps.c.

Fixes: e60b6fffca7b ("exit: Add and use make_task_dead.")
