I've split the git archive generation into three steps:

1. generate pure tarball
2. append top-level cmake directory to all tarballs
3. compress the archive

This was inspired by D118252 <https://reviews.llvm.org/D118252> and can be considered an alternative
approach for all projects to have access to the shared cmake
directory when building in standalone mode.
