Bug description:
  [Impact]
  No method to configure PAM services used (hard-coded to "lightdm"). This is required in some cases, e.g. when running Ubuntu on the phone we want to use a different PAM stack. By making this configurable the phone can have a package that overrides the default.

  [Test Case]
  1. Set a different PAM stack in the LightDM configuration:
   [SeatDefaults]
   pam-service=custom-service
  2. Start LightDM
  3. Log in
  Expected result:
  PAM modules in "custom-service" are run, user is logged in.
  Observed result:
  PAM modules in "lightdm" are run, user is logged in. (feature not yet supported)

  [Regression Potential]
  Low, fix is just replacing hard-coded values with a configuration lookup. Tested with regression tests.
