fix build (deploy): Actually include native assets in nupkgs

Native assets (libspark.dll/so) are copied to the outdir for local
builds, and packed in nupkg files for sdk releases. The dest path in the
package is different from the path in the outdir, so we configured
Copy/Pack as separate msbuild items. However, both had the same
Include="@(NativeWindows/LinuxAsset)", so Pack="false" in the Copy item
was overriding Pack="true" in the Pack item.
