Patch http-server to support cross-origin-isolation headers

[Scarabol]

Workaround for http-party/http-server#806 to be merged or http-server with --header argument support release, since 14.1.1 was released almost 3 years ago and header support added after.

Execution: https://github.com/Scarabol/ffmpeg.wasm/actions/runs/13493307016/job/37695139507

Tests still fail with:

1) [ffmpeg-core][mt] exec()
