Support lorri with home-manager

Prefer starting lorri with home-manager.

Note: I could have removed the `systemctl --user start lorri.service` line
before switching to home-manager by calling `systemctl --user enable
lorri.service`. This would have made a symlink in
`~/.config/systemd/user/default.target.wants`.
