setup: allow for prefix to be passed to git commands
In a future patch child processes which act on submodules need a little more context about the original command that was invoked. This patch teaches git to use the prefix stored in `GIT_INTERNAL_TOPLEVEL_PREFIX` instead of the prefix that was potentally found during the git directory setup process.
