t/interop: add test of old clients against modern git-daemon
This test just checks that old clients can clone and fetch from a newer git-daemon. The opposite should also be true, but it's hard to test ancient versions of git-daemon because they lack basic options like "--listen". Note that we have to make a slight tweak to the lib-git-daemon helper from the regular tests, so that it starts the daemon with our correct git.a version.
