Make GC_INIT optional for clients even if thread-local allocations enabled

* tests/test.c (GC_OPT_INIT): Do not define to GC_INIT() even if
THREAD_LOCAL_ALLOC; force define to GC_INIT() if TEST_EXPLICIT_GC_INIT
macro defined.
* thread_local_alloc.c [USE_PTHREAD_SPECIFIC || USE_WIN32_SPECIFIC]
(GC_malloc_kind): Check keys_initialized before GC_getspecific call
(fall back to GC_malloc_kind_global if keys_initialized is false).
