Add safe filter for raw args (vagrant) (#141)

src/molecule_plugins/vagrant/modules/vagrant.py: Add safe filter for raw args

Since molecule ansible/molecule#3887, the
jinja is now autoescaping, which leads to things like:

virtualbox.customize ['modifyvm', :id, '--natdnshostresolver1', 'on']

in the Vagrantfile.

Add some "safe" filters to solve this.
