samples: tests: Fix usb.audio.headset test

PerMac · nashif · commit 0fb58735f1ae · 2021-02-11T13:57:31.000-05:00
The sample was failing twister test with a timeout because there was
no pass/fail criteria for it (nothing was tested). The fix adds
harness on consolse and some output that can be verified.
