torture: Add --allcpus argument to the kvm.sh script
Leaving off the kvm.sh script's --cpus argument results in the script
testing the scenarios sequentially, which can be quite slow. However,
having to specify the actual number of CPUs can be error-prone.
This commit therefore adds a --allcpus argument that causes kvm.sh to
use all available CPUs.
