nixos/xss-lock: add module (NixOS#40619)
`xsslock` (which was originally packaged in 6cb1d1a) is a simple screensaver which connects a given screen locker (e.g. `i3lock`) with `logind`. Whenever `loginctl lock-sessions` is invoked the locker will be used to lock the screen. This works with its power management features (e.g. `lid switch`) as well, so the PC can be locked automatically when the lid is closed. The module can be used like this: ``` { services.xserver.enable = true; programs.xss-lock.enable = true; programs.xss-lock.lockerCommand = "i3lock"; } ```
