Remove 'ifdef USE_SPIN_LOCK' which is always false in gc_locks.h

(fix commit 9a20535)

* include/private/gc_locks.h [!GC_WIN32_THREADS && GC_PTHREADS
&& USE_PTHREAD_LOCKS && !GC_ASSERTIONS && NO_PTHREAD_TRYLOCK
&& USE_SPIN_LOCK] (UNCOND_LOCK): Define to
pthread_mutex_lock(&GC_allocate_ml) instead of GC_lock().
