[6.0] Different versions of `NuGet.Commands.dll`s between source-build and Microsoft build

### Describe the Bug

Sourcebuild has 3 copies of `NuGet.Commands.dll`, compared to just 1 copy in the Microsoft-built SDK. The version numbers are also different: `6.0.3-rc.32767+c60eee85ec0109bdda894806b167bb4d55f75183` vs `6.0.3-rc.1+c60eee85ec0109bdda894806b167bb4d55f75183.c60eee85ec0109bdda894806b167bb4d55f75183`, though the commit sha is the same.
