Ensure that TTL/hop count stats display correctly
Ensure that TTL/hop count stats display correctly

This prevents a "TTL not reported" message when there are no hops.

This also ensures that the min and max TTL and buckets are displayed
in the machine readable output.

MAXTTL in the machine readable output now displays the maximum TTL,
not the minimum TTL.
