fix data race in timer_create with SIGEV_THREAD notification
in the timer thread start function, self->timer_id was accessed without synchronization; the timer thread could fail to see the store from the calling thread, resulting in timer_delete failing to delete the correct kernel-level timer. this fix is based on a patch by changdiankang, but with the load moved to after receiving the timer_delete signal rather than just after the start barrier, so as not to retain the possibility of data race with timer_delete.
