libpod: do not call (*container).Config()

Browse Source 
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]
