sway: import NIXOS_OZONE_WL into systemd
Without this, even if you configure a preference for Electron apps to
use Ozone by setting `NIXOS_OZONE_WL=1`, GUI apps launched through
systemd user services use XWayland, since the variable is not set in
their environment.

This fixes that issue by importing it, like we do other variables.
