swoole proc_open doesn’t comply with php7.4 new features

[duan-feng]

Please answer these questions before submitting your issue. Thanks!

1. What did you do? If possible, provide a simple script for reproducing the error.

php7.4 proc_open 支持传入数组作为命令，支持null和重定向描述符。但swoole钩子版本proc_open都不支持。
示例代码如下
<?php
use function Swoole\Coroutine\run;
run(function () {
$res = proc_open(['echo', 'ok'], [['null'], ['pipe', 'w'], ['redirect', 1]], $pipes);
echo stream_get_contents($pipes[1]);
fclose($pipes[1]);
echo 'terminate: ' . proc_close($res) . "\n";
});

上面这段代码放到容器外执行，则没有问题。

2. What did you expect to see?
   ok
   terminate: 0

3. What did you see instead?
   PHP Fatal error: Uncaught TypeError: proc_open() expects parameter 1 to be string, array given in test.php:42
   Stack trace:
   #0 test.php(42): proc_open(Array, Array, NULL)
   编译出错 #1 {main}
   thrown in test.php on line 42

4. What version of Swoole are you using (show your php --ri swoole)?
   php --ri swoole:
   swoole
