Remove ulele/deepcopier in favor of JSON deep copy

We have a very high performance JSON library that doesn't need to
perform code generation. Let's use it instead of our questionably
performant, reflection-dependent deep copy library.

Most changes because some functions can now return errors.

Also converts cmd/podman to use jsoniter, instead of pkg/json,
for increased performance.
