Move intermediate file into intermediate dir (dotnet#5981)

The intermediate file, cmake.definitions, is moved into
the intermediate directory: bin/obj/OS.Arch.Conf/

The script won't emit error for not having the cmake
results because some systems (Windows) do not use Cmake
and users might use "skipnative".

Fixes #5976
