proc_open failed because Pty is not supported in Swoole

Please answer these questions before submitting your issue.

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

When I run this code:

<?php
Swoole\Runtime::setHookFlags(SWOOLE_HOOK_ALL);
Swoole\Coroutine\run(function () {
    $descriptorspec = [
        ['pty'],
        ['pty'],
        ['pty'],
    ];
    $process = proc_open(["echo", "1"], $descriptorspec, $pipes);

    var_dump($pipes);

    var_dump(fread($pipes[2], 8192));

    $return_value = proc_close($process);

    echo "command returned $return_value\n";
});

I got a warning and the process failed to start:

PHP Warning:  proc_open(): pty pseudo terminal not supported on this system

When I ran the same code without Swoole, it worked fine

<?php

$descriptorspec = [
  ['pty'],
  ['pty'],
  ['pty'],
];
$process = proc_open(["echo", "1"], $descriptorspec, $pipes);

var_dump($pipes);

var_dump(fread($pipes[2], 8192));

$return_value = proc_close($process);

echo "command returned $return_value\n";

2. What did you expect to see?

Running process should work fine without warning and output 1

3. What did you see instead?

PHP Warning:  proc_open(): pty pseudo terminal not supported on this system

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