Bug description:
  [Impact]
  Having the same configuration variable defined in two places causes LightDM to a double free and potentially crash.

  [Test Case]
  1. Install two configuration files in /etc/lightdm/lightdm.conf.d which both define the same variable.
  2. Run LightDM
  Expected result:
  LightDM runs correctly.
  Observed result:
  LightDM double frees a variable (seen with valgrind) and can crash.

  [Regression Potential]
  Low. The fix is not to double free the variable.
