git-daemon won't start up if its project directory (here /git) doesn't exist. If we try to create it using the test harness, then we're racing whether we manage to connect to the backdoor vs. the startup speed of git-daemon. Instead, use systemd-tmpfiles, which is guaranteed(?) to run before network.target and thus before git-daemon.service starts.
