checkpoint-tester script tests gem5's checkpoints by
using gem5 to produce a series of checkpoints, each with
a specified interval. After that, for all K > 1,
each of K-th produced checkpoint is used by gem5 to produce
the {K+1}-th checkpoint. The newly produced checkpoint will
be compared against the {K+1}-th checkpoint that was
previously produced.
Previously, in the tester script, the inputs to
`--take-checkpoints X,Y` was `(interval, interval)`.
The intention was to restore the N-th checkpoint and to run
the simulation for `interval` ticks.
According to the current configs/common/Options.py file,
`--take-checkpoints X,Y` means `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,
and this change addresses this problem.
