tests: Make DPP protocol failure testing more robust

Wait explicitly for the DPP-NOT-COMPATIBLE event when going through
protocol testing with local failures instead of just waiting for a fixed
0.1 second duration. This prevents a test failure at least in
dppauth_resp_status_failure in a case where the failing operation may be
delayed under heavy CPU load.
