mod_tokenauth: Fix expiry lasting one second too much Because the code was using `< now` in a lot of places, things expiring at the current second wouldn't be marked as expired. It isn't noticeable in real-world scenarios but I wanted to create OAuth 2.0 tokens valid for 0 second in integration tests and it wasn't possible. By using `<=` instead of `<`, we make sure tokens don't live a single millisecond more than what they are supposed to.
