Move D-Bus finder class constructors

Three classes in this repository search for D-Bus interfaces and call
a callback when interfaces are found:
- DBusInterfacesFinder
- CompatibleSystemTypesFinder
- DeviceFinder

The constructors of these three classes may immediately call the
callback.  For this reason, these constructors should not be used in the
initialization list of constructors in other classes.  Otherwise the
callback may be called before the other class is fully initialized,
leading to unpredictable behavior.

Move usage of these three constructors from initialization lists to
constructor bodies.

Tested:
+ CompatibleSystemTypesFinder
  + Test where compatible system types interface already exists on D-Bus
    + Verify callback is called immediately
  + Test where compatible system types interface does not already exist
    on D-Bus
    + Verify callback is called later when interface is added
  + Verify callback is passed the correct data
+ DeviceFinder
  + Test where device interface already exists on D-Bus
    + Verify callback is called immediately
  + Test where device interface does not already exist on D-Bus
    + Verify callback is called later when interface is added
  + Verify callback is passed the correct data
