Adding read permissions for /proc/net/dev and /proc/*/net/dev seems
harmless enough to me, as these are just summaries, not information
about particular packets. So good to add from my POV.

  Guest session can't read "/proc/net/dev" and/or "/proc/*/net/dev"

Bug description:
  I'm customizing my guest sessions in Xubuntu 15.04 and discovered that
  xfce4-netload-plugin can't show current net traffic. After
  investigating netload plugin source code, I've found that a possible
  reason for this strange behaviour is that guest sessions are unable to
  read /proc/net/dev and/or /proc/<PID>/net/dev.

  Could you please review current apparmor profile for lightdm-guest-
  session so it can get read access to /proc/net/dev?
