Hit in multiple PR CI:

• Move "Patches Apply Cleanly" check to the top #2197
• Improve NocgoOpenSSL.md #2198

It seems to occur in only some builders at a time. The built-in 3 retry steps all failed. For #2197, retrying the pipeline didn't work.

The upstream issue golang/go#66894 seems related because it fails in similar-looking files, but the actual deep errors are very different, like source file is not valid UTF-8:

golang/go#66894 is also old. 2024 with no new comments, and no human comments at all.

I suspect this is closely related to:
