oauth: Disallow synchronous DNS in libcurl
There is concern that a blocking DNS lookup in libpq could stall a
backend process (say, via FDW). Since there's currently no strong
evidence that synchronous DNS is a popular option, disallow it entirely
rather than warning at configure time. We can revisit if anyone
complains.
Per query from Andres Freund.
