Title: Makefile.include: Fix git version string generation for external projects

For contiki projects not located in the contiki tree the generation of `RELSTR` in `Makefile.include` will return the description for the projects git but not for the contiki git.

This can be fixed by setting `--git-dir` explicitely to `${CONTIKI}/.git`
