Bluetooth: tests: Add privacy configuration for test basic_conn_encrypt

Add privacy configuration when using the split controller for the test
basic_conn_encrypt. The handling with or without controller based
privacy affects the RPA handling in the host due to different
connection complete events being used. This affects the overall pairing
procedure as the addresses are inputs to the pairing functions.
