device-nokia-n900: improve user experience on i3 (MR 4157)

- fix wifi signal quality display, since /proc/net/wireless is no longer
  available in omap kernel
  Suggested-by: DvaMishkiLapa <thesame.personal@gmail.com>

- add `polkit-elogind` so tools like `loginctl poweroff` and `nmtui` do not
  require sudo under i3wm
