deps: bump to go-criu v8.3.0

go-criu v8.3.0 switches to protobuf-go-lite, which helps to remove
google.golang.org/protobuf dependency from here, reducing the runc
binary size from ~16M to ~14M.

The only missing piece is proto.String, proto.Bool, proto.Int32 etc.
helpers that return a pointer to a given variable. Those are replaced
by a generic mkPtr, which in turn is to be replaced by the new builtin
once Go < 1.26 is no longer supported.
