Even Brenden 660882d883 nixos/displayManager: add XDG_SESSION_ID to systemd user environment
xss-lock needs XDG_SESSION_ID to respond to loginctl lock-session(s)
(and possibly other session operations such as idle hint management).
This change adds XDG_SESSION_ID to the list of imported environment
variables when starting systemctl.

Inspired by home-manager, add importVariables configuration.

Set session to XDG_SESSION_ID when running xss-lock as a service.
