zend call stack fix freebsd code path.

The typo in HAVE_PTHREAD_ATTR_GET`_`STACK (might be due to pthread_attr_get_np being different from
Linux's pthread_getattr_np) led to this code path never get called on FreeBSD.
Anyway, like Linux the first condition alone is enough, pthread_attr_getstack being present
 even in the 9.x release's serie.
