OpenMPI: tell it where libcuda.so is (#36784)

Browse source 
starting with the 5.0.x release stream the cuda related configury
items in Open MPI once again need --with-cuda-libdir so that
libcuda.so can be found at configure time, otherwise no cuda
support unless someone copies libcuda.so to
$CUDA_HOME/lib64

related to #36760
