Projects: Enable flake8 checking for all python modules
Enable flake8
checking for all python modules by default. Previously this was only done for new-style configuration files or if the developer enabled the checking manually via atlas_install_python_modules(... POST_BUILD_CMD ${ATLAS_FLAKE8})
. The latter is now obsolete and could be removed from all packages in a future MR (but it doesn't hurt either).
Closes ATLINFR-3889.
