Sniff test: adjust two test files to match

This removes two expected errors due to the tokenizer change made in the previous commit.

### `Generic.Arrays.DisallowLongArraySyntax`

The code on line 13 is a parse error, so the sniff no longer throwing an error for it should not be our concern.
```php
$var = array;
```

### `Squiz.PHP.CommentedOutCode`

The code which triggered the warning on line 35 was a docblock written as a block comment and not really commented out code anyway, so this could be considered a fix for a false positive.
```php
/*
 * The listeners array.
 *
 * @var array(PHP_CodeSniffer_Sniff)
 */
```
