RFR: 8368029: Several tests in httpserver/simpleserver should throw SkipException

Fri Sep 19 10:16:26 UTC 2025

I propose a change to have these tests listed appropriately as "skipped" rather than "passing" on Windows. I'm also taking the opportunity to save an indentation level since we can throw a `SkipException` early in all the related methods.
