version suffixes are inconsistent in 11.0.0-preview.2

[corngood]

When I build this release I get a mix of final vs. 26159.11 in the version suffixes of the artifacts:

aspnetcore-runtime-11.0.0-preview.2.final-linux-x64
aspnetcore-runtime-composite-11.0.0-preview.2.final-linux-x64
aspnetcore-targeting-pack-11.0.0-preview.2.final-linux-x64
dotnet-apphost-pack-11.0.0-preview.2.final-linux-x64
dotnet-crossgen2-11.0.0-preview.2.final-linux-x64
dotnet-nethost-11.0.0-preview.2.final-linux-x64
dotnet-runtime-11.0.0-preview.2.final-linux-x64
dotnet-sdk-11.0.100-preview.2.final-linux-x64
dotnet-symbols-all-11.0.100-preview.2.26159.112-linux-x64
dotnet-symbols-sdk-11.0.100-preview.2.26159.112-linux-x64
Private.SourceBuilt.Artifacts.11.0.100-preview.2.26159.112.linux-x64

In preview.1 they all ended up with the build id suffix. Usually they match release.json, and our build scripts (nixpkgs) have always depended on this. Was this an intentional change?

This seems to explain the problem. It looks like --branding repodefault will be required for preview 2 and possibly not for future versions.
