[Raphael Isemann via lldb-commits]

https://github.com/Teemperor created https://github.com/llvm/llvm-project/pull/226486

This test is flaky on Linux, macOS and Windows. The usual failure on macOS is as follows:

```

```

The test is already skipped on all platforms except macOS. This patch skips it on all platforms.
