After merging #13998 it was observed that the `docker-py` task was still
failing with the same error on `main`. The original quick-fix had
placed the full-build (`make`) call too late in the process. This
commit moves it up to right before the `make install` call which was
resulting in an error.
Again, a further future commit is planned to re-work and simplify the
entire cache setup. This is only a quick fix to make branch-builds
pass.
