Major fixes to podman ps --format=json output

A number of fields were never being populated. Populate them as
best we can.

Add a new field, exited, to indicate whether the exit code has
meaning (IE, the container has exited).

Fix handling of running time - it stops ticking when the
container stops. There is further work needed here, I suspect.
