kernel: let rt_thread_idle_excute loop until there is no dead thread

Browse Source 
Out side world is difficult to tell whethere there is dead thread
remaining. If rt_thread_idle_excute only do one cleanup, it's hard to
finish cleanups outside the idle thread. So let is loop and do all the
cleanups in one call.
