molecule_vagrant/modules/vagrant.py: Fix libvirt option driver test (#89)

In commit "Set cpu to qemu64 with qemu driver", defined?() has been
used to check if provider['options']['driver'] is defined but it seems
that the test is not doing what I was expecting. Switching to .has_key?
is fixing the issue.
