vfio: selftests: Extend container/iommufd setup for passing vf_token

Browse source

A UUID is normally set as a vf_token to correspond the VFs with the
PFs, if they are both bound by the vfio-pci driver. This is true for
iommufd-based approach and container-based approach. The token can be
set either during device creation (VFIO_GROUP_GET_DEVICE_FD) in
container-based approach or during iommu bind (VFIO_DEVICE_BIND_IOMMUFD)
in the iommu-fd case. Hence extend the functions,
vfio_pci_iommufd_setup() and vfio_pci_container_setup(), to accept
vf_token as an (optional) argument and handle the necessary setup.

No functional changes are expected.
