GIT_VERSION is not available as a config.h variable, because it's rendered into version.h during builds. Let's rework jinja2 rendering to also parse version.h. No functional change, the new variable is so far unused. I guess this will make partial rebuilds a bit slower, but it's useful to be able to use the full version string.
