serialize: add explicit calls for finishing serialization
These new calls will do three things:
1. in case of FILE* stuff: flush any pending bytes onto the fd, just in
case
2. seal the backing memfd
3. seek back to the beginning.
Note that this adds sealing to serialization: once we serialized fully,
we'll seal the thing off for further modifications, before we pass the
fd over to the target process. This should add a bit of robustness, and
maybe finds a bug or two one day, if we accidentally write to a
serialization that is complete.
