Process.detach: avoid singleton class creation

* process.c (Init_process): subclass Thread as Process::Waiter
  (rb_detach_process): use Process::Waiter instead of singleton class

* test/ruby/test_process.rb (test_process_detach): new test

* inits.c (rb_call_inits): call Init_Thread before Init_process to
  ensure Process::Waiter may be a subclass of Thread

Thanks to headius for reporting [Bug #10231]
