Fix the presence of managed build logs on Windows (dotnet#62446)

When analyzing PR failures I noticed that the log / wrn / err / binlog
combo only gets produced on Unix runs. I think this is also a bug
I made in the build script refactoring, the logging parameters
were used for the cmake build instead of the managed build.
[I can add a second set of logging parameters for the cmake build
phase if needed but I believe it wasn't there before my change.]

Thanks

Tomas
