- Add has_sriov manifest entry to enable SR-IOV testing

- Only SR-IOV enabled interfaces will run the functional tests
- Add info/sriov-check_{interface} template test that check
  if SR-IOV is enabled for an interface
- Update SR-IOV LXD and LXD_VM tests to depend on
  interface-specific SR-IOV capability check
