Describe the bug

sni.dll is not include in the result of dotnet publish for netfx.
Looks like #137, but finally found it also happen with directly reference.

To reproduce

Tested with MS.SqlClient 1.0.19221.1-Preview/1.0.19189.1-Preview, dotnet-sdk 3.0.100-preview8-013656/2.2.400, net48(runtime).

1. dotnet new console;
2. change TargetFramework to net472;
3. dotnet add package Microsoft.Data.SqlClient --version 1.0.19221.1-Preview;
4. dotnet publish
   See sni.dll is included in the build result bin\Debug\net472\x64\SNI.dll but not the publish result bin\Debug\net472\publish. And SqlClient failed to init with the published program as an result.

Expected behavior

sni.dll should also be included with dotnet publish for netfx
