Added compatibility matrix for docker-build script (#268)

- matrix -m argument for build-docker.sh that lists compatible OS + ROCm combinations.
- ${DISTRO} is now case-insensitive.
- Added note to README.md to mention this flag.
- Removed --build-arg AMDGPU_RPM=${ROCM_RPM}, which is no longer used
