itimer: Fix mistaken overflow prevention in overrun counting.

itimer_transition just returns the new number of overruns, doesn't
add to an existing number; it's the caller who must add to the
existing number, and avoid arithmetic overflow in that addition.
(Should maybe push the addition into itimer_transition but that
requires a little more work -- also it should maybe saturate at
DELAYTIMER_MAX rather than INT_MAX.)

While here, fix another arithmetic overflow in overrun counting in
ptimer_intr.
