Hi,

Recently I realized that we are having issues with setscene tasks (for docker-moby and cni recipes) where the packages were rebuild even already have their tasks in the sstate mirror and bitbake-diffsigs not showing any difference.
This is the sample of the output that I was getting:
```

```

After some debugging I found that the "failed with exit code 1" comes from this line http://git.yoctoproject.org/cgit/cgit.cgi/poky/tree/meta/classes/sstate.bbclass#n764:
```
localdata.setVar('SRCPV', d.getVar('SRCPV'))
```

The root cause is because the cni and docker-moby recipes are using named SRC_URI (a.k.a http://...;name=foo), setting the PV with it and were not setting the SRCREV_FORMAT which consequentially not set the SRCPV accordingly.

Setting the SRCREV_FORMAT for cni and docker-moby recipes fixed the issue, but I also suspect that the following recipes are potentially having the same issue:
```
$ grep -r PV | grep SRCREV_
recipes-core/runx/runx_git.bb:PV = "v1.0-git${SRCREV_runx}"
recipes-core/runv/runv_git.bb:PV = "0.4.0+git${SRCREV_runv}"
recipes-containers/docker/docker-ce_git.bb:PV = "${DOCKER_VERSION}+git${SRCREV_docker}"
recipes-containers/docker/docker-moby_git.bb:PV = "${DOCKER_VERSION}+git${SRCREV_moby}"
recipes-containers/cri-o/cri-o_git.bb:PV = "1.22.0+git${SRCREV_cri-o}"
recipes-containers/kubernetes/kubernetes_git.bb:PV = "v1.22.2+git${SRCREV_kubernetes}"
recipes-containers/cri-tools/cri-tools_git.bb:PV = "1.21.0+git${SRCREV_cri-tools}"
recipes-containers/crun/crun_git.bb:PV = "0.18+git${SRCREV_crun}"
recipes-networking/cni/cni_git.bb:PV = "v0.8.0+git${SRCREV_cni}"
recipes-devtools/yq/yq_git.bb:PV = "1.13.1+git${SRCREV_yq}"
recipes-devtools/go/go-build_git.bb:PV = "0.1-git${SRCREV_runx}"
```

I can send a patch to fix cni and docker-moby but unfortunately I don't have resources to test the other mentioned recipes.
