[fix] For parallel build with serial hdf5 issue warning and skip hdf5.

Browse Source 
We rely on parallel hdf5 for a parallel build of OPM flow. Otherwise
compilation will fail. Hence if this is a parallel build but only a
serial hdf5 library is found, we now issue an informative warning and
deactivate hdf5/parallel restart.

Closes OPM/opm-common#3405
