thread.c: fix for non-scalar pthread_t

* configure.in (rb_cv_scalar_pthread_t): pthread_t is not required
  to be a scalar type.
* thread.c (fill_thread_id_string, thread_id_str): dump pthread_t
  in hexadecimal form if it is not a scalar type, assume it can be
  represented in a pointer form otherwise.  based on the patch by
  Rei Odaira at [ruby-core:62867].  [ruby-core:62857] [Bug #9884]
* thread_pthread.c (Init_native_thread, thread_start_func_1),
  (native_thread_create): set thread_id_str if needed.
* vm_core.h (rb_thread_t): add thread_id_string if needed.
