Better support for Swoole Runtime

Question	Answer
JIRA issue	IBX-XXXX
Type	improvement
Target Ibexa version	v4.2
BC breaks	no

Replaces #146 due to lack of response.

SCRIPT_FILENAME is not set in Swoole

You can reproduce it with

export APP_ENV="prod"
export APP_DEBUG="0"
export APP_RUNTIME="Runtime\Swoole\Runtime"

# public/index.php
<?php

use App\Kernel;
$_SERVER['APP_ENV'] = 'dev';
$_SERVER['APP_DEBUG'] = true;

$_SERVER['APP_RUNTIME_OPTIONS'] = [
    'host' => '0.0.0.0',
    'port' => 8080,
    'mode' => SWOOLE_BASE,
    'settings' => [
        \Swoole\Constant::OPTION_WORKER_NUM => swoole_cpu_num() * 2,
        \Swoole\Constant::OPTION_ENABLE_STATIC_HANDLER => true,
        \Swoole\Constant::OPTION_DOCUMENT_ROOT => dirname(__DIR__).'/public'
    ],
];

require_once dirname(__DIR__).'/vendor/autoload_runtime.php';

return function (array $context) {
    return new Kernel($context['APP_ENV'], (bool) $context['APP_DEBUG']);
};

@xrow Informing you that this is being merged as you're the original author.

Please do keep in mind that Swoole (and other similar runtimes) remain unsupported, which means that this is done on the "best effort" basis. There might be other issues that might prevent it from working correctly. If there are any, feel free to reach out to me.
