cyclictest: Add long option --laptop to preserve battery power

Some people running cyclictest on laptops don't want to automatically
take advantage of the trick that prevents the power management to
transition to high cstates, since it eats up their battery power.

Allow them to suppress this feature with --laptop

This will result in power latency results of course.
