configure.in: split SET_THREAD_NAME

Browse source 
* configure.in: separate SET_CURRENT_THREAD_NAME, which can set
  the name of current thread only, and SET_ANOTHER_THREAD_NAME,
  which can set the name of other threads.
* thread.c (rb_thread_setname): use SET_ANOTHER_THREAD_NAME.  OS X
  is not possible to set another thread name.
* thread_pthread.c (native_set_thread_name, thread_timer): use
  SET_CURRENT_THREAD_NAME.
