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.
