[Jenkins] Publish bundle.zip and msbuild.zip as GH statuses as well. (#4238)

This also requires a maccore bump, commit list for xamarin/maccore:

* xamarin/maccore@443e956edc [release] Rename bundlefull.zip to bundle.zip. (#848)
* xamarin/maccore@5020593b3e Remove jenkinsfile from d15-8, tom-swifty doesn't track normal release branches. (#849)
