When packaging an Sf4 application as a PHAR archive using globs at various locations (`Kernel`, `services.yaml`) most glob files are not found because the `glob()` PHP method [does not support PHAR streams](https://stackoverflow.com/questions/8203188/unexpected-problems-with-php-phar).

Using the regex fallback instead when operating inside PHAR archives fixes the behavior for me.

## Examples:

`src/Kernel.php::configureContainer()`:

```php
$loader->load($confDir.'/{services}'.self::CONFIG_EXTS, 'glob');
```

Expected behavior: `config/services.yaml` inside PHAR archive is found and parsed
Actual behavior: the file will not be loaded

`config/services.yaml` (hard-coded in Kernel without using glob pattern)

```yaml
    App\:
        resource: '../src/*'
        exclude: '../src/{Entity,Migrations,Tests,Kernel.php}'
```

Expected behavior: service classes in `src/` will be found and auto-wired
Actual behavior: services are not auto-wired because the class files are not found
