Motivation for this change

Required to build msbuild without silly workarounds to do nuget restore successfully. Packages added with older nuget add are then not found by newer nuget that is used in the msbuild build scripts.

There are newer versions of nuget, just not in the mono/nuget-binary repo from which this package was originally built. The downloads from https://www.nuget.org/downloads ran for me in mono just fine, but I did not test extensively, so I'll stick to mono/nuget-binary for now.
