Ability to use lru_cache(user_function) was only introduced in Python 3.8. Buster has Python 3.7. This causes startup failure in Buster. Fix this by using the older API for lru_cache instead of the new one. Tests: - On stable and testing, starting the Plinth daemon and visiting the performance page should work. - Adding a print statement in the _get_url() method shows that it is only called once, ever.
