fix(docker): streamline environment variable logging in l4t images

- Consolidated and relocated environment variable logging commands to improve
  clarity and avoid redundancy during the Docker build process.
- Added `platforms` property to `docker-compose` build stages to ensure builds
  explicitly target `linux/amd64` platform.
- Improved debugging by logging requirement file contents during installation
  and ensuring Python package installations include Nvidia's PyPI index.

Issue NMO-794
