regulators: Obtain config file name from D-Bus

Determine the correct JSON configuration file name based on the values
in the D-Bus compatible systems interface.

Also support a default configuration file name for systems that do not
use the compatible systems interface.

Tested:
* Verified correct config file name found on Rainier system
  * When phosphor-regulators starts before entity-manager
  * When phosphor-regulators starts after entity-manager
* Verified correct config file name found on Everest system
  * When phosphor-regulators starts before entity-manager
  * When phosphor-regulators starts after entity-manager
* Error cases
* For full test plan see
