Roll web platform tests

Includes:

* Some updates to package.json's update-wpt script.
* Fixes to wpt-config.json and tuwpt-config.json to match upstream changes.
* Changed to-upstream/html/webappapis/timers/settimeout-setinterval-handles.html to be less strict, because harness changes have likely caused setTimeout/setInterval to be called somewhere outside the test.
* Improvements to wpt-server.js, to avoid infinite server startup attempts and otherwise clean up the code.
