fix stale lock when allocation of ctor queue fails during dlopen
queue_ctors should not be called with the init_fini_lock held, since it may longjmp out on allocation failure. this introduces a minor TOCTOU race with p->constructed, but one already exists further down anyway, and by design it's okay to run through the queue more than once anyway. the only reason we bother to check p->constructed at all is to avoid spurious failure of dlopen when the library is already fully loaded and constructed.
