[webauthn] Merged Pull Request: Clarify the U2F Attestation format to have a single certificate

agl has just merged arnar's pull request 836 for https://github.com/w3c/webauthn:

== Clarify the U2F Attestation format to have a single certificate ==
The [U2F Raw Message Format](https://fidoalliance.org/specs/fido-u2f-v1.2-ps-20170411/fido-u2f-raw-message-formats-v1.2-ps-20170411.html#h3_registration-response-message-success) only allows for a single attestation certificate in U2F responses.

This PR reflects this in the U2F Attestation Format to reduce the chance of misunderstanding when implementing the server verification.
