mvapich2: extended the fabrics variant description (#19860)
The point of this variant is to give the end user an option to use system installed fabrics such as mofed instead of upstream fabrics such as rdma-core. This was found to avoid run time errors on some systems. Co-authored-by: nithintsk <nithintsk@github.com>
