mod_http_oauth2: Reject non-local hosts in more code paths
We're not issuing tokens for users on remote hosts, we can't even
authenticate them since they're remote. Thus the host is always the
local module.host so no need to pass around the host in most cases or
use it for anything but enforcing the same host.
