Now that checkasm can automatically fall back to RDCYCLE, it is safe to
enable this for forward compatibility with kernel versions mitigating
the "Cycle Drift" side channel attack.

Where available, this should also reduce measurement noise, since
kernel and hypervisor cycles should no longer be counted.
