Bug description:
  [Impact]
  xserver-allow-tcp=true option no longer works with X.org 1.17.

  [Test Case]
  1. Edit /etc/lightdm/lightdm.conf and set [SeatDefaults] xserver-allow-tcp=true
  2. Start LightDM
  3. Attempt to connect to the X server using TCP

  Expected result:
  Able to connect

  Observed result:
  Unable to connect

  [Regression potential]
  Low. X.org changed their default behaviour from listen by default to listen if "-listen tcp" is passed as a command line flag. This is just the equivalent change in LightDM. Since this is a new flag to X.org if a user was to use another X server there is a risk it would not understand that flag. However it seems unlikely since X.org is the only actively developed X server.
