Fix podman stop -t -1 CID

Currently if a user specifies a negative time to stop a container the
code ends up specifying the negative time to time.Duration which treats
it as 0. By settine the default to max.Unint32 we end up with a positive
number which indicates > 68 years which is probably close enough to
infinity for our use case.

Fixes: containers#21811
