Fixed bug: onWorkerStop cannot be triggered.

[twomiao]

1. 修复worker 进程无法触发信号，导致onWorkerStop() 无法执行。

$signals = [SIGINT, SIGTERM, SIGHUP, SIGTSTP, SIGQUIT, SIGUSR1, SIGUSR2, SIGIOT, SIGIO];
foreach ($signals as $signal) {
    //   pcntl_signal($signal, SIG_IGN, false); 移除信号屏蔽，重新注册会重写master 信号。
    // Rewrite master process signal.
   static::$globalEvent->onSignal($signal, [static::class, 'signalHandler']);
}

2. 修复swoole exit() 发生异常：

onWorkerStart
^CWorkerman[start.php] stopping ...
onWorkerStop
PHP Fatal error:  Uncaught Swoole\ExitException: swoole exit in /mnt/c/users/twomiao/desktop/workerman/src/Worker.php:1921
Stack trace:
#0 /mnt/c/users/twomiao/desktop/workerman/src/Worker.php(1192): Workerman\Worker::stopAll()
#1 [internal function]: Workerman\Worker::signalHandler()
#2 {main}
  thrown in /mnt/c/users/twomiao/desktop/workerman/src/Worker.php on line 1921
worker[none:2878] exit with status 65280
Workerman[start.php] has been stopped

try { // Ignore Swoole ExitException: Swoole exit. exit($code); } catch(\Exception $e) { }

3. 复现代码：

<?php

use Workerman\Events\Swoole;
use Workerman\Worker;

require __DIR__ . "/vendor/autoload.php";

Worker::$eventLoopClass = Swoole::class;
Worker::$stopTimeout = 15;
$worker = new Worker("http://0.0.0.0:8888");
$worker->count = 1;
$worker->onMessage = static fn ($connection) => $connection->send("hello world");

$worker->onWorkerStart = static fn (Worker $worker) => print "onWorkerStart\n";
$worker->onWorkerStop = static fn (Worker $worker) => print "onWorkerStop\n";
Worker::runAll();
