Fix Crossgen2 test concurrency on Windows (#45433)

In my previous attempt at fixing the test concurrency w.r.t. to
multiple "RunOnly" tests exercising the same "BuildAndRun"
executable compiled with Crossgen2,

https://github.com/dotnet/runtime/pull/44492

I have apparently used the wrong escaping in the batch (cmd)
version of the script so that the fix doesn't work on Windows.
This change is fixing this deficiency.

Thanks

Tomas
