[autoroll] Decrease chromite->chromium roll frequencies from 0m to 24h.

Some sheriffs are complaining that it's a bit too noisy. We don't really
need chromite changes rolled asap into chromium, so this decreases the
roll frequency to once per day. Should help make things less noisy (and
decrease the load on chrome's CQ!)
