crypto/x509: TestPlatformVerifier failures on Windows due to broken connections [1.22 backport]

[gopherbot]

@rolandshoemaker requested issue #56791 to be considered for backport to the next 1.22 minor release.

@gopherbot please open backport issues for this. It's an incredibly noisy test which is currently only failing on the release branches. Those branches currently have the better tests enabled, so we should just backport https://go.dev/cl/548976 and remove these old broken ones to make the builders happy.

This is now approved for backporting. @rolandshoemaker Is it convenient for you to mail the backport CLs? Thanks.

[rolandshoemaker]

Yes I can do that, thanks!
