We should make update notifier use RESINRC_DATA_DIRECTORY correctly, and make the CLI resilient to any update notifier errors too, so we ignore any kind of failures here (while still reporting them to sentry).

With #698 solved this is now much lower priority: these failures no longer break the CLI, and the update notifier can be disabled entirely with NO_UPDATE_NOTIFIER.

We should still fix this to obey RESINRC_DATA_DIRECTORY, so that users with non-writable ~/.config still get update notifications, but I'll drop the priority.

Closing this issue in favour of #1667 and #1669, and also because update-notifier has had a couple of major-version updates (now at 4.1.0) since this issue was created.
