refactor: remove function deleting obsolete ULWGL files on launch

- This was only appropriate to do going from pre-release to stable release, and, at this point, most users are expected to not have any ULWGL files. However, for future releases, calling this function to clean up a new set of obsolete files will not be ok due to the risk of breaking other applications that do not use the Lutris API to acquire it automatically
