Bugfix: ptask should use expand_add for exec tasks

The variable in the system is the same for ptasks, so use expand_add to
reuse the element if it exists in the system. Similar as it's done for
communications

New model for parallel tasks: host/model:ptask_BMF

Implement a new solver for lmm::System based on BMF (Bottleneck max
fairness) objective.

BMF provides a more realistic sharing of heterogeneous resources as used
by parallel tasks.

Enable it using: --cfg=host/model:ptask_BMF instead of ptask_L07.

SimGrid compilation from source now requires a new library: Eigen3.
