podman image scp never enter podman user NS

Podman image scp should never enter the Podman UserNS unless it needs to. This allows for
a sudo exec.Command to transfer images to and from rootful storage. If this command is run using sudo,
the simple sudo podman save/load does not work, machinectl/su is necessary here.

This modification allows for both rootful and rootless transfers, and an overall change of scp to be
more of a wrapper function for different load and save calls as well as the ssh component
