touchpad: reduce the jumping cursor warnings to 5 per day

It's been a while since we really could do something about those jumps, so let's assume most of these are informative and not a bug in libinput. For that let's not spam the user's journal and ratelimit it to a handful a day.

Per day because that increases the chance of an error being present in the recent logs if the user does search for it.
