topo: add NIC to numa domain on g5.48xlarge platforms

Since G5 platforms did not support PCIe technologies properly,
the NIC generated by NCCL in the topology file reported a numa
domain of -1. NCCL further assigns it the same system ID as the CPU.
CPUs with the same system ID are not connected to each other
during topology generation. This results in a seg fault during
topology path computation as GPUs are not able to find a
path to the NIC.
