git: force-fully ignore the environment variable GIT_VERSION

While it used to be possible to override the version shown in `git version` via `make GIT_VERSION=...`, the same was not true of the environment variable `GIT_VERSION`. However, that changed in Git's 992bc5618f2 (GIT-VERSION-GEN: fix overriding GIT_VERSION, 2024-12-20). To force the build process to derive the version shown in the output of `git version`, let's forcefully un-set the environment variable during the build.
