Test -Dmigration_path_for_coreos_toolbox on CentOS Stream 9

The code behind -Dmigration_path_for_coreos_toolbox is meant for Red Hat
Enterprise Linux 8 and 9.  Hence, it makes sense to use CentOS Stream 9
to run the 'unit tests' on the corresponding code path.

Note that, just like Fedora, Podman prefers crun(1) as its OCI runtime
on CentOS Stream 9 [1,2].
