Miguel Angel Ajo 8db658b02b Make sure ~/.ssh/known_hosts exists before calling ssh-keygen -R
Our vagrant file makes use of ssh-keygen -R to remove any old key
related to an IP address from known_hosts.

But ssh-keygen fails and makes the local.sh exit with failure
(error 2) if the ~/.ssh/known_hosts file does not exist.
