mod_http_oauth2: Add support for the "openid" scope
This "openid" scope is there to signal access to the userinfo endpoint,
which is needed for OIDC support.
We don't actually check this later because the userinfo endpoint only
returns info embedded in the token itself, but in the future we may want
to check this more carefully.
