checkpoint: handle XDG_RUNTIME_DIR
For (almost) all commands which podman passes on to a OCI runtime XDG_RUNTIME_DIR is set to the same value. This does not happen for the checkpoint command. Using crun to checkpoint a container without this change will lead to crun using XDG_RUNTIME_DIR of the currently logged in user and so it will not find the container Podman wants to checkpoint. This bascially just copies a few lines from on of the other commands to handle 'checkpoint' as all the other commands. Thanks to Giuseppe for helping me with this. For 'restore' it is not needed as restore goes through conmon and for calling conmon Podman already configures XDG_RUNTIME_DIR correctly. Signed-off-by: Adrian Reber <areber@redhat.com>
