Fix opcache optimizer info for time_nanosleep

This can also return an array. See
https://www.php.net/manual/en/function.time-nanosleep.php#refsect1-function.time-nanosleep-returnvalues

> If the delay was interrupted by a signal, an associative array will be
returned with the components:
>
> - seconds - number of seconds remaining in the delay
> - nanoseconds - number of nanoseconds remaining in the delay

Sending a SIGUSR1 to the below program would trigger this behavior.

```
pcntl_signal(\SIGUSR1, function ($signo, $signinfo) {
    echo "Handling a signal $signo\n";
});
echo "Sleeping for 100 seconds\n";
var_export(time_nanosleep(100, 0));
```

The incomplete signature existed since c88ffa9a5.
No phpt tests existed for time_nanosleep returning an array
