Removing a non existing container API should return 404

Currently we were overwrapping error returned from removal
of a non existing container.

$ podman rm bogus -f
Error: failed to evict container: "": failed to find container "bogus" in state: no container with name or ID bogus found: no such container

Removal of wraps gets us to.

./bin/podman rm bogus -f
Error: no container with name or ID "bogus" found: no such container

Finally also added quotes around container name to help make it standout
when you get an error, currently it gets lost in the error.
