Modify sniff to allow $ (this) in @return

Problem/Motivation

Currently in https://drupal.org/node/1354#types it's said that $this can be used
in @return when a main class is being returned but the sniff don't allow it.

Checking the code I see that if there is an $ will be return an error:

if (strpos($return->getValue(), '$') !== false) {
                    $error = '@return data type must not contain "$"';
                    $this->currentFile->addError($error, $errorPos, '$InReturnType');
}

Here is the issue (#1533250-36: Many coding standards clean-ups in locale module) where has been detected that the phpcs don't allow $this to be used in @return

Proposed resolution

Change the rules to allow $this for a @return
