test: Add handover support with BlueZ 5

Bluetooth pairing information is removed before any handover requests
are sent to a remote device. This adds support to allow pairing
information removal with BlueZ 5.

The information about the default adapter is no longer publicly
available with BlueZ 5. The user can therefore select the bluetooth
adapter whose paired devices are removed. If no adapter is specified
the first adapter is used.
