[PATCH] Fix git detection when cloned as submodule

[Dan Church]

Hi GNUNet devs!

I found an issue where VERSION and PACKAGE_VERSION would always be set to 'unknown' if gnunet was cloned as a git submodule.

Steps to repro:

mkdir superproject
cd superproject
git init
git submodule add https://git.gnunet.org/gnunet.git
cd gnunet
contrib/get_version.sh

At this point, 'unknown' will print if this is still an issue.

With the attached fix, '0.19.2-6-gbe0ba43d7' will print.
