Add a helper function, vfio_device_set_vf_token(), to set or override a vf_token. Not only at init, but a vf_token can also be set via the VFIO_DEVICE_FEATURE ioctl, by setting the VFIO_DEVICE_FEATURE_PCI_VF_TOKEN flag. Hence, add an API to utilize this functionality from the test code. The subsequent commit will use this to test the functionality of this method to set the vf_token.
