GHA/non-native: skip OpenBSD WebSocket tests to mitigate job timeouts

Trying to avoid the occasional ~6-minute long delays seen in the OpenBSD
since last week. The long delay causes the CI job to timeout and fail:
https://github.com/curl/curl/actions/workflows/non-native.yml?page=2&query=branch%3Amaster

The exact reason is or test number is unknown. I base this attempt on
looking at the first occurrences and possible patches that may be
related.

The issue was first seen in CI within PR #17136:
```
