signal.c (rb_f_kill): remove rb_thread_polling() because this
has no good effect and makes meaningless 100ms delay. 1)
when sending signal to another process, waiting has just silly.
2) when sending signal to current process, 100ms is often not
enough time to wait. It depend on kernel behavior. And,
rb_thread_polling() doesn't make sense anyway. When rb_thread_alone()
is true, it doesn't wait at all and Process.kill() users don't
expect threading changes Process.kill() behavior. [Bug #7560]
