Fix vagrant rsync

The git repository contains some blind symlink that cause issues when syncing
with default vagrant rsync setting.

E.g.
Godeps/_workspace/src/github.com/docker/docker/pkg/symlink/testdata/fs/g
is pointing to non-existing path, causing vagrant to fail on:

    rsync error: some files/attrs were not transferred
vagrant-libvirt support

This commits adds basic support to use the Vagrantfile with vagrant-libvirt
plugin.
