abdc5961c3: Fix starting the firewall
e090701e2d: Order before sysinit
Solely use sysinit.target here instead of multi-user.target because we
want to make sure that the iptables rules are applied *before* any
socket units are started.
The reason I've dropped the wantedBy on multi-user.target is that
sysinit.target is already a part of the dependency chain of
multi-user.target.
To make sure that this holds true, I've added a small test case to
ensure that during switch of the configuration the firewall.service is
considered as well.
Tested using the firewall NixOS test.

You can now run a test in the nixos/tests directory directly using
nix-build, e.g.
$ nix-build '<nixos/tests/login.nix>' -A test
This gets rid of having to add the test to nixos/tests/default.nix.
(Of course, you still need to add it to nixos/release.nix if you want
Hydra to run the test.)
