Bug description

Using any commands of systemctl with the --user flag like systemctl list-unit-files --user --state=enabled with systemd native support activate gives the error: Failed to connect to bus: No such file or directory

To Reproduce

Steps to reproduce the behavior:

1. Activate native systemd adding wsl.nativeSystemd = true; to /etc/nixos/configuration.nix
2. Run systemctl list-unit-files --user --state=enabled

Expected behavior

The command execute without errors.

In the example command it should display all units.

Logs

Similar to #165 doing systemctl list-unit-files --user --state=enabled with native systemd support turned off works perfectly:

UNIT FILE                STATE   PRESET
emacs.service            enabled enabled
nixos-activation.service enabled enabled
dbus.socket              enabled enabled
gpg-agent-ssh.socket     enabled enabled
gpg-agent.socket         enabled enabled

5 unit files listed.

While with native systemd support turned off errors:

Failed to connect to bus: No such file or directory
