After recent merges of breeze where we check whether Docker needs rebuild we do not need to fix all files in the context.
Most of the times the build will not be triggered (and setup.py, Dockerfile package.json etc. will not change). So it is enough just to fix permissions for those sensitive files and do not loose time for listing and fixing all the files in the context.
This will save 5 or so seconds for every build and decrease overall build script complexity.
