thread.c: clear atfork functions

Browse source 
* thread.c (rb_thread_atfork, rb_thread_atfork_before_exec): do
  nothing unless working fork is available.
* thread_sync.c (rb_mutex_abandon_all): define only if working
  fork is available.
* thread_sync.c (rb_mutex_abandon_keeping_mutexes): ditto.
* thread_sync.c (rb_mutex_abandon_locking_mutex): ditto.
* thread_win32.c (gvl_init): never used.
