Subject: [PATCH] libcontainerd: change the digest used when restoring

For current implementation of Checkpoint Restore (C/R) in docker, it
will write the checkpoint to content store. However, when restoring
libcontainerd uses .Digest().Encoded(), which will remove the info
of alg, leading to error.
