Prevents git commands run in a recipe from moving up past ${WORKDIR}
when searching for a .git directory, and thus prevents them from
detecting the parent OE-core .git directory. Fixes several
reproducibility issues where recipes would use the OE-core version as
the recipe version due to git walking up the tree.
