It is convenient to assume that everybody who wants to build & test Git has access to a working `iconv` executable (after all, we already pretty much require libiconv). However, that limits esoteric test scenarios such as Git for Windows', where an end user installation has to ship with `iconv` for the sole purpose of being testable. That payload serves no other purpose. So let's just have a test helper (to be able to test Git, the test helpers have to be available, after all) to act as `iconv` replacement.
