CPU: Intel Atom should follow the same rule as ARM

See: https://forum.duniter.org/t/duniter-powcluster-js-utilise-mes-8-coeurs-a-100/3608/17

Indeed, we divide the CPU value by 2 for ARM (empiric rule): https://github.com/duniter/duniter/blob/da85e4c3ba8e18a66b0c216335454473e1c205ae/app/modules/prover/lib/engine.ts#L38-L40

It seems Atom CPU suffer the same problem, and needs to have the CPU% value divided by 2 as well.
