Refactor window-manager-logout

Browse source 
`sudo systemctl suspend` wasn't working because it required a secure password
prompt to read the user's password for `sudo`. The recommended way to call
`shell-command` with a `sudo` command (from what I read online) is to set
`default-directory` to `/sudo::` before calling `shell-command`. This works just
fine, so I refactored the function, `window-manager-logout`.
