device-tree-compiler FTBFS in Kinetic

I've copied what I hope is the relevant part of the log below.

Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

I'm not sure how this ever built; the issue is that the override d/rules uses to tell setuptools-scm what the version should be is:

  export SETUPTOOLS_SCM_PRETEND_VERSION=$(DEB_VERSION_UPSTREAM)

However, DEB_VERSION_UPSTREAM is blank because pkg-info.mk hasn't been imported. I'll open a PR upstream in salsa but I'm attaching a patch here for us to workaround the issue in the meantime.
