fix: remove support libraries from LD_PRELOAD, keep only stub libraries

- GetLibraryNames() now only returns stub libraries that intercept GPU API calls
  - NVIDIA: libcuda.so, libnvidia-ml.so
  - AMD/Hygon: libamdhip64.so
- Removed libteleport.so and libaccelerator from LD_PRELOAD
  - libteleport is loaded dynamically by stub libraries
  - libaccelerator is used by ggo binary, not for GPU call interception
- All libraries remain available in container via /opt/gpugo/libs mount
- Updated comments to clarify the distinction
