rcutorture: Add --no-initrd argument to kvm.sh
This commit adds the --no-initrd argument to kvm.sh, which permits
initrd to be contained in a root partition specified by the --bootargs
argument. Without --no-initrd, the kernel build expects an initrd
directory in the same rcutorture directory that contains bin and configs.
