Support multiple D-Bus interfaces in getSubTree()

The utility function getSubTree() only allows a single D-Bus interface
to be specified.

This does not match the corresponding GetSubTree D-Bus method, which
allows multiple D-Bus interfaces to be specified.

Add a getSubTree() overload that accepts multiple D-Bus interfaces.

Tested:
* Existing getSubTree() function
  * Test where it is successful
  * Test where it fails due to a D-Bus error
* New getSubTree() function
  * Test where zero interfaces are specified
  * Test where one interface is specified
  * Test where multiple interfaces are specified
  * Test where it is successful
  * Test where it fails due to a D-Bus error
