Add instructions for adding the user to the kvm group

[markdryan]

This doesn't seem to happen automatically.

@markdryan -- I believe you fixed this in the readme, but I am still seeing issues when following along. I'm on xenial, and as a normal user that is part of group kvm, I still see;

$ ccloudvm create go/src/github.com/intel/ccloudvm/workloads/clearcontainers-3.x.yaml
Booting VM with 4000 MiB RAM and 2 cpus
Error: Failed to launch qemu : exit status 1, Could not access KVM kernel module: Permission denied
failed to initialize KVM: Permission denied

Any suggestions?

And, heads up that in the directions you say that after making the adjustment (group addition) you can then just type ccloudvm connect. If you had this failure, it would've been at @ the create stage first, so you'll likely want to say, 'rerun ccloudvm create foo.'

while a new terminal didn't solve it, a reboot did. never mind!

@egernst Just out of a matter of interest. Are you running any other hypervisors on your system, e.g., Virtual box?

@markdryan - no, nothing additional
