util: Fix checkpoint-tester.py checkpoint parameter
Previously, the inputs to `--take-checkpoints X,Y` was
`(interval, interval)` with attention to restore the N^th checkpoint
and to run the simulation for `interval` ticks.
Currently, the parameter `X` is the starting tick of the simulation,
while `Y` is the number of ticks to be simulated after tick `X`.
Therefore, `X` should be the starting tick of the N^th checkpont.
