tests/checkasm: increase number of runs in between measurements

Sometimes, when measuring very small functions, rdtsc is not accurate enough
to get a reliable measurement. This increases the number of runs inside the
inner loop from 4 to 32, which should help a lot. Less important when using
the more precise linux-perf API, but still useful.

There should be no user-visible change since the number of runs is adjusted
to keep the total time spent measuring the same.
