Wrap missing container errors with container ID

Browse Source 
While playing around with podman system df, I saw that my container
database was in bad state.  Basically podman new about containers
that were no longer in container/storage.

The podman system df was just erroring out early stating "container does not exist"
with no indicator of which container.

This Patch wraps the podman system df errors to indicate which container does not exist.
It also logs errors on containers that get into this state, but continues on to work on
all containers.
