[tests/dnf] work around dnf packaging issue (#72249)

Change:
- In this test we end up upgrading dnf (and python3-dnf) so that we can
  test its new logging behavior. However, the latest Fedora 32 dnf had a
  packaging issue which caused it to not pull in the latest
  python3-libdnf. This is fixed, but not synced out to mirrors yet.
  Fixing it in this test will get CI passing again in the meanwhile.

Test Plan:
- CI
