The user is only reading the config, so creating a copy turns out to be extremely expensive. With this change, listing containers is 1.39 times faster than before.

[NO NEW TESTS NEEDED] as it is not a functional change.

Does this PR introduce a user-facing change?

Improve the performance of `podman ps`.
