Peter Korsgaard c07aafa087 package/Makefile.in: set GIT_DIR=. in {HOST, TARGET}_MAKE_ENV 
A number of packages try to detect if they are running in a git repo and run
git describe at build time instead of using the hard coded version number if
it succeed, leading to odd version numbers as they end up picking up the
Buildroot git version if building inside a Buildroot git checkout, E.G.:

rauc --version
rauc 2023.11-562-g9c954953b4+

This is because rauc builds with meson and uses vcs_tag:

https://github.com/rauc/rauc/blob/v1.11/meson.build#L168-L171

https://mesonbuild.com/Reference-manual_functions.html#vcs_tag

Another example is micropython, where we already work around it by passing
GIT_DIR=.

In the context of Buildroot the packages are never built in their own git
checkout, so pass GIT_DIR=.  to ensure git doesn't walk back up the
directory tree and finds the Buildroot git repo, which fixes the rauc (and
similar) issues.
