Matthew Heon 19a03976f7 Retain a copy of container exit file on cleanup ...

When cleaning up containers, we presently remove the exit file
created by Conmon, to ensure that if we restart the container, we
won't have conflicts when Conmon tries writing a new exit file.

Unfortunately, we need to retain that exit file (at least until
we get a workable events system), so we can read it in cases
where the container has been removed before 'podman run' can read
its exit code.

So instead of removing it, rename it, so there's no conflict with
Conmon, and we can still read it later.

Fixes: #1640
