f13d0adb - Ensure that builds within the cache aren't considered Git repositories (#1782)

Ensure that builds within the cache aren't considered Git repositories (#1782) ## Summary Some packages encode logic to embed the current commit SHA in the version tag, when built within a Git repo. This typically results in an invalid (non-compliant) version. Here's an example from `pylzma`: https://github.com/fancycode/pylzma/blob/ccb0e7cff3f6ecd5d38e73e9ca35502d7d670176/version.py#L45. This PR adds a phony, empty `.git` to the cache root, to ensure that any `git` commands fail. Closes https://github.com/astral-sh/uv/issues/1768. ## Test Plan - Create a tag on the current commit, like `v0.5.0`. - Build `pylzma`, using a cache _within_ the repo: ``` rm -rf foo cargo run venv cargo run pip install "pylzma @ https://files.pythonhosted.org/packages/03/d8/10ef072c3cd4301a65a1b762b09eefa02baf8da23b9ea77ebe9546499975/pylzma-0.5.0.tar.gz" --verbose --cache-dir bar ```
