Prefix config glob path

- If the default glob path is detected in the set of glob paths, prefix it with the value of `getcwd()` prior to passing it off to the application. This ensures the ConfigListener will be able to glob all paths correctly.
- Done in the bootstrap script (`public/index.php`) instead of `config/application.config.php` as Apigility writes to that file when creating or removing a module -- which means that the value of `getcwd()` would normally be expanded when written back. By making the change in the bootstrap, we can ensure the value remains untouched by Apigility.
