Subject: [PATCH] Enable roll forward in our .NET Core exes

This changes our build to mark all of our .NET Core applications as
rolling forward on major / minor versions of the .NET framework.
Presently our tools ship inside both .NET Core 2 and 3 SDKs. This
setting allows our tools to run unmodified in both settings.
