Update to latest CRIU RPC protobuf definition

This updates to the latest CRIU RPC protobuf definition from criu-dev.

Now, that CRIU protobuf files are licensed as 'MIT', the protobuf
definition can also be included in the repository.

Main motivation for this change is to provide LsmMountContext in
runc.
