nixos/switch-to-configuration: reload user units
When rebuilding you have to manually run `systemctl --user daemon-reload`. It gathers all authenticated users using `loginctl list-user` and runs `daemon-reload` for each of them. This is a first step towards a `nixos-rebuild` which is able to reload user units from systemd. The entire task is fairly hard, however I consider this patch usable as it allows to restart units without running `daemon-reload` for each authenticated user.
