gh-149879: Fix test_httpservers on Cygwin

• Issue: Enhance Cygwin support #149879

BaseHTTPSServerTestCase and test_https_client() still fail with this PR. But I propose disabling the ssl module on Cygwin for now, since many tests are failing.

These tests pass with the ssl PR gh-150419.

Disabling it seems a good way to fix the problems indeed. We need to investigate more the reason why SSL on cygwin is struggling before fixing each test one by one (I prefer having the big picture first because we may introduce subtle issues if we do a case-by-case)

I changed my mind. It's no longer needed to disable the ssl module, since I have a working fix for ssl on Cygwin: PR gh-150419.
