tools: optimize docker image and fix launchpad builds

- Earlier fixes removed .git which potentially failed building the
  examples as esp-idf does git describe during builds. Added them back
  anad build works now.
- Removed the dormant bits from the docker-image
- Added ninja-jobs option for better resource utilization during host
  tool builds
- Added back the linux installation as we do need ability to run
  chip-tool from the container.
