zuma: fix selftest regression
New widevine TA check_protection now returns HDCP_NO_DIGITAL_OUTPUT
during authentication.
Additionally, it requires authentication within 3 seconds which means
declaring DP_CONNECT isn't fast enough (which waits 2.5 seconds before
triggering HDCP auth).
Bug: 243411142
Test: "echo 1 > /dev/hdcp2"
