Fixing a test in DeviceUniqueAttestationTest

The EC key check for generating a device unique attestation from a
non-strongbox keymaster instance left out the
TAG_DEVICE_UNIQUE_ATTESTATION_TAG, so the test should fail since the
attestation should succeed. This commit adds the tag into the parameters
passed into attestation.
