CMake: (fix) parallel HDF5 1.14.0 and MPI

• The other day, the HDF group fixed a small mistake in their generation of the HDF5 CMake configuration file which solves the missing target MPI::MPI_C. This fixed will be part of future versions of HDF5 (1.8, 1.10, 1.12 and 1.14). As a result we only need to call find_package(MPI) for HDF5 1.14.0 version.

Actions: (fix) apt-get update

• Call apt-get update to ensure we get the latest version of the latest packages.

This pull request is a result of the discussion of https://github.com/HDFGroup/hdf5/pull/2400. In this discussion @lrknox mentions that only HDF5 1.14.0 has this missing MPI::MPI_C target. All future releases of HDF5 will contain the fix mentioned in the pull request https://github.com/HDFGroup/hdf5/pull/2400. Therefore, I adjusted the implementation such that the call to find_package(MPI) will only be done for HDF5 1.14.0.

I have tested the implemented using HDF5 1.12.1 and 1.14.0. Both of them work as expected.
