[tests] --no-use-pep517 in kubevirt_conformance (#72015)

Change:
- This enables the inventory_kubevirt_conformance test to pass again on
  freebsd.
- This was due to a google-auth version bump. The dep chain looks like
  this: openshift -> kubernetes -> google-auth -> aiohttp -> multidict

Test Plan:
- ansible-test integration inventory_kubevirt_conformance --remote
  freebsd/12.0
