[WIP PATCH 01/18] rev-parse: add --internal-cwd and --internal-git-dir for tests

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

--internal-cwd is obvious, no way else to expose it for testing.

--internal-git-dir is introduced because --git-dir prepares its output
suitable for scripting. For tests, it must be exactly what git stores.
