test: support disabling KVM by setting NO_KVM

KVM fails on the Ubuntu ppc64el autopkgtest runners: ``` $ /usr/bin/qemu-system-ppc64el -enable-kvm -cpu host [...] ioctl(KVM_CREATE_VM) failed: 22 Invalid argument PPC KVM module is not loaded. Try modprobe kvm_hv. qemu-system-ppc64el: failed to initialize kvm: Invalid argument $ modprobe kvm_hv modprobe: ERROR: could not insert 'kvm_hv': No such device ``` Signed-off-by: Benjamin Drung <[email protected]>
