MDL-39087 Fix missing cronlib inclusion in file_storage::cron()

This is not actually related to MDL-38259 but it was discovered while
running unit tests for file_storage. When running the tests for this
class separately, the cronlib.php was not included (it is included
when this method is normally called during cron execution).
