vagrant-libvirt: install the latest version

The pinned version is already too old and is failing in CI due to:
```
Error message given during initialization: Unable to resolve dependency:
user requested 'vagrant-libvirt (= 0.12.2)'
```

Let's try the latest and see if the reason for pinning the old one
still exists.
