Enable checkpoint/restore for /dev/shm
When Podman is running a container in private IPC mode (default), it
creates a bind mount for /dev/shm that is then attached to a tmpfs
folder on the host file system. However, checkpointing a container has
the side-effect of stopping that container and unmount the tmpfs used
for /dev/shm. As a result, after checkpoint all files stored in the
container's /dev/shm would be lost and the container might fail to
restore from checkpoint.
To address this problem, this patch creates a tar file with the
content of /dev/shm that is included in the container checkpoint and
used to restore the container.
