[v4.9-rhel] Ensure that containers do not get stuck in stopping

[TomSweeneyRedHat]

The scenario for inducing this is as follows:

1. Start a container with a long stop timeout and a PID1 that ignores SIGTERM
2. Use podman stop to stop that container
3. Simultaneously, in another terminal, kill -9 pidof podman (the container is now in ContainerStateStopping)
4. Now kill that container's Conmon with SIGKILL.
5. No commands are able to move the container from Stopping to Stopped now.

The cause is a logic bug in our exit-file handling logic. Conmon being dead without an exit file causes no change to the state. Add handling for this case that tries to clean up, including stopping the container if it still seems to be running.

Fixes #19629

@edsantiago and/or @cevich I keep running into the below error on the "Validate rawhide Build" test. Other than pressing "try again", is there anything else to do?

Seems to be this https://github.com/containers/podman/blob/1b049941640a7df3d0fc272f3acb32727b6179b8/contrib/cirrus/setup_environment.sh#L337-L338

Can you try removing that dnf line? And maybe removing it from the other two places that also dnf it? At least that might get you past Validate and onto other tests. (Which of course might fail)

[cevich]

Another suggestion: Remove the rawhide validation (or possibly ALL rawhide everything) from CI, I don't think old-rawhide is useful on a RHEL release branch.

[TomSweeneyRedHat]

Turning off Rawhide seems to have done the trick. Ready for review and happy green tests buttons. Ditto #23089
