fix: add /auditwheel_src to git safe directories (#378)

The volume bound to the manylinux/musllinux for `/auditwheel_src` uses the host uid for file ownership which is different from the uid used inside the containers.

git now checks uid to allow/deny actions.

This adds `/auditwheel_src` to git safe directories to allow setuptools_scm to infer auditwheel version inside the containers.
