[Buildroot] [PATCH 1/2] package/Makefile.in: set GIT_DIR=. in {HOST, TARGET}_MAKE_ENV

Hi all,

This will also break the usage of package/environment-setup. The
GIT_DIR=. leaks in
the environment script `environment-setup` useful when a developer
wants to use a Buildroot
generated SDK to build an external project.
So, on a developer machine after sourcing the environment script, all
git commands fail:

$ git status
fatal: not a git repository: '.'
