Luke Granger-Brown f2a91ec2b7 nixos/tests/gitdaemon: deflake by using systemd-tmpfiles
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.
