logd: correct for number of elements in prune

(cherry pick from commit d745c72af8f367b2b1595c36fa922ca1f44388e6)

Chatty logs would distort the average log size by elevating the
elements, but not the size. Add statistical collection for the
number of elements that report chatty, and subtract that from
the number of elements to improve the pruning estimate. Pick
minElements as 1% rather than 10% of the total with this more
accurate number of elements, to a minumum of 4.
