Add multi stage Dockerfile to build Trace Compass

1. The stage "packager" installs the minimum package needed to
compile tracecompass.
2. Then it will copy the project inside the container then run
the command to build tracecompass.
3. After the build, it will go to the next stage and this stage will
just have the bare minimum configuration to run tracecompass.
4. It will copy tracecompass already installed into the new stage.
