mod_http_oauth2: Strip unknown extra fields from client registration
We shouldn't sign things we don't understand!
RFC 7591 section-2 states:
> The authorization server MUST ignore any client metadata sent by the
> client that it does not understand (for instance, by silently removing
> unknown metadata from the client's registration record during
> processing).
Prevents grandfathering in of unvalidated data that might become used
later, especially since the 'additionalProperties' schema keyword was
removed in 698fef74ce53
