[msbuild] Set the working directory before executing 'dotnet build' in the ComputeRemoteGeneratorProperties task.

[rolfbjarne]

If the project in question needs a custom NuGet.config, this NuGet.config file
will be in a base directory of where the .NET executable is located. I'm not
certain what the current directory is when executing dotnet in this task, so
make it explicit in case it's a different path.

This in particular might affect us for remote tests using .NET previews:
