metrics: Round down 24h5m of daily usage to 24h.

Since the metrics_daemon only updates usage statistics every 5 minutes,
we'll often report slightly more than 24 hours of usage for devices that
are active for exactly 24 hours in a day (e.g. kiosk devices). Work
around this by rounding down from 24h5m to 24h.

We don't round down any larger numbers because they could be due to
unrelated bugs, and we don't want to mask them.
