mvapich: fix RPATH issues and infiniband build 

The rpath fix elimnated too much and thus disabled the mpichversion
binary. Diasabling dlopen for infiniband libraries fixes the build for
the infinband interface option.

With this patch scalapack completes all tests for the infiniband and
omnipath interface selection. However, ethernet is still broken with
for the scalapack tests. See https://github.com/NixOS/nixpkgs/issues/258599
