Vagrantfile: fallback on 'varant_variables.yml.sample'

When using a vagrant command from the root directory of the repo, it
throws an error if no 'vagrant_variables.yml' file is present.

```
Message: Errno::ENOENT: No such file or directory @ rb_sysopen - /home/guits/workspaces/ceph-ansible/vagrant_variables.yml
```
