BUGFIX: Invalid return codes in kpod

Set the exitsdir for kpod back to /var/run/crio... so kpod can benefit
from the container exit file.

Because 0 is the int32 blank value, kpod needs its own container state
struct with the omitempty removed so it can actually display 0 in
its default json output.
