使用 Guzzle 上传大数据时报错, 方法从 POST 变成了 PUT

### 问题描述
下述代码在本地测试没有问题, 使用 Ubuntu 的 docker 镜像时, 报错.
请求的 `POST` 方法变成 `PUT`

### 测试docker镜像

```sh
docker run -it --name guzzle-swoole liuende501/swoole-guzzle-test "/bin/bash"

# 启动后
cd /var/opt/
php guzzle/httpbin.php

# 调试
USE_ZEND_ALLOC=0 valgrind -s php guzzle/httpbin.php
```

    $data['json']['Image'] = $imgBase64;
    $client = new Client([

    try {
        $res = $client->request('POST', '', $data);
        echo "request end" . PHP_EOL;
        echo $res->getBody()->getContents();
    }catch (\Throwable $e){
        echo  $e->getMessage();
    }
    echo PHP_EOL . "end" . PHP_EOL;
});
```

### 你期待的结果是什么？实际看到的错误信息又是什么？
从 httpbin.org 响应我的请求数据, 实际看到的是 
```
The cURL request was retried 3 times and did not succeed. The most
likely reason for the failure is that cURL was unable to rewind the body of the request and subsequent retries resulted
in the same error. Turn on the debug option to see what went wrong.
```

这个问题就要看源码了。

```php
#guzzle vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php
    private function applyBody(RequestInterface $request, array $options, array &$conf): void
    {
        $size = $request->hasHeader('Content-Length')
            ? (int) $request->getHeaderLine('Content-Length')
            : null;

// Send the body as a string if the size is less than 1MB OR if the
        // [curl][body_as_string] request value is set.
        if (($size !== null && $size < 1000000) || !empty($options['_body_as_string'])) {
            $conf[\CURLOPT_POSTFIELDS] = (string) $request->getBody();
            // Don't duplicate the Content-Length header
            $this->removeHeader('Content-Length', $conf);
            $this->removeHeader('Transfer-Encoding', $conf);
        } else {
            $conf[\CURLOPT_UPLOAD] = true;
            if ($size !== null) {
                $conf[\CURLOPT_INFILESIZE] = $size;
                $this->removeHeader('Content-Length', $conf);
            }
            $body = $request->getBody();
            if ($body->isSeekable()) {
                $body->rewind();
            }
            $conf[\CURLOPT_READFUNCTION] = static function ($ch, $fd, $length) use ($body) {
                return $body->read($length);
            };
        }

// If the Expect header is not present, prevent curl from adding it
        if (!$request->hasHeader('Expect')) {
            $conf[\CURLOPT_HTTPHEADER][] = 'Expect:';
        }

// cURL sometimes adds a content-type by default. Prevent this.
        if (!$request->hasHeader('Content-Type')) {
            $conf[\CURLOPT_HTTPHEADER][] = 'Content-Type:';
        }
    }
```

你的文件大于了1MB，所以设置了`CURLOPT_UPLOAD`；

HOOK_CURL 是由 library 实现的，再来看下

https://github.com/swoole/library/blob/038e7d29d847f3e02b335c955cedc6cd4bbef949/src/core/Curl/Handler.php#L670-L672

设置了 method 为 `PUT`
