benchmarks/imb: upgrade to 2021.3

This port was very outdated: releases notes are available at
<https://github.com/intel/mpi-benchmarks/releases>.

The PDF is no more included but the user guide is available at
<https://software.intel.com/en-us/imb-user-guide>.

Also modernize the port and switch from OpenMPI 3 to OpenMPI4 (optiopnal,
MPICH still being the default).

Chase the upgrade of MPICH2.

Since I'm there, pet portlint where needed, e.g. by removing oblsolete
MD5 checksums.

The idea of IMB is to provide a concise set of elementary MPI
benchmark kernels. With one executable, all of the supported
benchmarks, or a subset specified by the command line, can be run.
The rules, such as time measurement (including a repetitive call
of the kernels for better clock synchronization), message lengths,
selection of communicators to run a particular benchmark (inside
the group of all started processes) are program parameters.
