Rename masakari_venv_pip_packages to exclude from repo_build process

Variable masakari_venv_pip_packages was renamed in order to exclude from
repo-build process, as it fails in case of Jinja inside *_pip_packages.

As this variable collects all other *_pip_packages lists, repo_build
will still have all mentioned packages, so it's safe to rename this var.
