Add a selftest, vfio_pci_sriov_uapi_test.c, to validate the
SR-IOV UAPI, including the following cases, iterating over
all the IOMMU modes currently supported:
 - Setting correct/incorrect/NULL tokens during device init.
 - Close the PF device immediately after setting the token.
 - Change/override the PF's token after device init.
