emulator_fuzz: Add test plugin

This plugin creates an org.ofono.test.EmulatorFuzz interface on path
/test.  Currently only one method is implemented, SetIndicatorActive.

SetIndicatorActive("DistractedDrivingReduction", True|False) allows to
activate / deactivate the HF indicator via +BIND unsolicited
notification.
