Bug description:
  [Impact]
  The XDMCP and VNC servers in LightDM allow connections on any network interface. It is desirable for these to be limited to a particular interface to limit who can connect (i.e. only allow local connections on 127.0.0.1).

  [Test Case]
  1. Enable the VNC server in LightDM in lightdm.conf:
  [VNCServer]
  enabled=true
  listen-address=127.0.0.1
  2. Start LightDM
  With this setup you should only be able to make a local connection.

  [Regression potential]
  Low. If the option is not set LightDM has the old behaviour.
