The test has been disabled in https://github.com/dotnet/runtime/pull/39003, I am moving it to 6.0

This is now only failing on OSX. Maybe https://github.com/dotnet/runtime/pull/38334 IsSignalIgnored implementation is not ok for OSX?

FWIW I've tried to reproduce it on my mac book and I've failed ;)
