Cleanup: removed MPI dependencies

[miguelmaso]

I've started to try to launch distributed runs on a cluster (not working yet). I experienced some issues when precompiling HyperFEM, because of the dependencies (mismatch between the system libraries and the Julia libraries).

I find it better to remove the strong dependencies on HPC libraries that are not directly used by HyperFEM. Those are dependencies of the specific project using HyperFEM and HPC.

Note: the proper way to solve this issue is to create an extension package (HyperFEMDistributed) with the MPI libraries
