libpod: do not call (*container).Config()
Access the container's config field directly inside of libpod instead of
calling `Config()` which in turn creates expensive JSON deep copies.
Accessing the field directly drops memory consumption of a simple
`podman run --rm busybox true` from 1245kB to 410kB.
[NO TESTS NEEDED]
