top: tweaks to vertical scroll management & 'i' toggle

The commit referenced below claims to disable vertical
scrolling when idle tasks weren't being shown. However
it really addresses only a point in time when that 'i'
toggle is keyed. Left untouched were the up/down keys.

So this commit will simply finish the job of disabling
vertical scrolling whenever tasks which have used some
CPU are the only ones which are currently being shown.
