Fix bluez config test failure on clang

This compile failure used to be a warning only but these days is a failure
for clang:

The need for BDADDR_NONE is obsolete now since the test does not rely on
those defines anymore. The main purpose is to check that bluetooth.h
is available which is already tested by using bacmp and bdaddr_t.
