Because our el_wake API didn't use explicit memory barriers between the
read/write synchronizations points TSAN reported data race such as the
one below:

Indeed even if the eventfd() API ensures the thread safety of the
write/read sequence we still have to ensure no more usage of the fd
itself is possible before closing it.
Thus we add an explicit memory barrier in the form of an atomic counter.

thr_queue_drain() seemed to assume that no other thread is running the
queue when used and thus started with an `atomic_store(&q->running_on,
id)` without taking care of the current `running_on` value.
But when destroying a queue (`thr_queue_destroy`) TSAN reported this
race:
WARNING: ThreadSanitizer: data race

Indeed when finishing to drain the queue, another would finished by:
do {
[…]
} while (!mpsc_queue_drain_end(&it, &thr_qnode_destroy));
atomic_compare_exchange_strong(&q->running_on, &id,
THR_QUEUE_NOT_RUNNING);
So after removing the last element of the queue (`mpsc_queue_drain_end`)
the queue's `running_on` is reset to THR_QUEUE_NOT_RUNNING.
But when destroying, the sole condition to immediately drain the queue
is:
if (mpsc_queue_push(&q->q, &n->qnode)) {
thr_queue_drain(q);
So the race is obvious here, as soon as the queued is emptied, the
destroying thread could already be freeing the queue while the previous
thread could still be trying to reset `q->running_on`.
To fix we now actually wait for the queue to be release before draining
it again.
