Subject: [PATCH] simgrid: 3.30 -> 3.31

- addition of the optional eigen dependency, used by a new simulation
  model (bmf) that looks very promising to take interference phenomena
  into account while remaining coarse-grained.
- enabled the new dependency by default as I think this is interesting
  for most users.
