Use packageSourceMapping to control source of NuGet packages

Contrary to common-sense, NuGet package sources are not ordered.
Thus, the existence of nuget_official.config is pointless as it was
an attempt to prefer already published .nupkgs over newly built
.nupkgs in post-GA builds.

Instead, NuGet introduced packageSourceMapping which is a more
powerful solution to address post-GA package resolution.
