Florian Klink 0084c41abf nixos/systemd: add remote-cryptsetup.target
/etc/crypttab can contain the _netdev option, which adds crypto devices
to the remote-cryptsetup.target.

remote-cryptsetup.target has a dependency on cryptsetup-pre.target. So
let's add both of them.

Currently, one needs to manually ssh in and invoke `systemctl start
systemd-cryptsetup@<name>.service` to unlock volumes.

After this change, systemd will properly add it to the target, and
assuming remote-cryptsetup.target is pulled in somewhere, you can simply
pass the passphrase by invoking `systemd-tty-ask-password-agent` after
ssh-ing in, without having to manually start these services.

Whether remote-cryptsetup.target should be added to multi-user.target
(as it is on other distros) is part of another discussion - right now
the following snippet will do:

```
systemd.targets.multi-user.wants = [ "remote-cryptsetup.target" ];
```
