update "Requires: g++" to "gcc-c++" in rpm package spec

[Priyankasaggu11929]

As part of the PR ROCm/gpu-operator#365, I'm trying to add "SLES support for AMD gpu-operator".

Part of the work requires adding a internal/kmmmodule/dockerfiles/DockerfileTemplate.sles.gim dockerfile template which will be installing the gim-dkms kernel module package in a container created with a SLES base image.

In SLES rpm package repos, the gcc-c++ package installs the g++ binary but it doesn't define Provides: g++ rather it defines Provides: gcc-c++ which also matches with what is provided by the same gcc-c++ package in RHEL/CentOS repos as well.

This PR proposes updating the gim-dkms package rpm spec to require gcc-c++ instead of the current g++ for resolving the dependency on g++ binary, so that the gim-dkms installation works on SLES OS as well.

---

Steps to verify/reproduce the "failed dependency" error w.r.t g++ on SLES OS:

• Dockerfile (only relevant part):

  FROM registry.suse.com/suse/sle15:15.6 AS builder
  
  RUN zypper --non-interactive addrepo \
      --no-gpgcheck \
      https://repo.radeon.com/amdgpu/6.2.2/sle/15.6/main/x86_64/ \
      amdgpu
  
  RUN zypper --non-interactive --gpg-auto-import-keys refresh
  
  RUN zypper --non-interactive install -y \
      kernel-default-devel \
      gcc-c++ \
      cmake \
      dkms \
      autoconf \
      automake
  
  RUN wget https://github.com/amd/MxGPU-Virtualization/releases/download/mainline%2F8.4.0.K/gim-dkms-8.4.0.K-0.noarch.rpm && \
      rpm -ivh gim-dkms-8.4.0.K-0.noarch.rpm && \
      rm gim-dkms-8.4.0.K-0.noarch.rpm

  results in error:

  2.392 error: Failed dependencies:
  2.392 	g++ is needed by gim-dkms-8.4.0.K-0.noarch

• while the gcc-c++ package coming from the SLES base container indeed provides the g++ binary:

  ❯ podman run -it --rm registry.suse.com/suse/sle15:15.6 /bin/bash
  b995e0b7bfa1:/ # zypper install gcc-c++
  
  
  b995e0b7bfa1:/ # zypper info --provides gcc-c++
