Add dependency on System.Runtime.Serialization.Primitives to make up for JSON.NET not including it

[davidfowl]

When running MVC without explicitly adding System.Runtime.Serialization.Primitives when running on the .NET CLI you'll get this error:

An unhandled exception has occurred while executing the request
      System.IO.FileNotFoundException: Could not load file or assembly 'System.Runtime.Serialization.Primitives, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

It's because of JamesNK/Newtonsoft.Json#618. DNX used to include this assembly so it wasn't needed but now it is. Until we sorta out netstandard and the process for building new style libraries we should add it as a dependency to MVC.Core.

I'll address this as part of #3908 (although I haven't run this as yet).

[davidfowl]

@pranavkm Try running HelloMvc (https://github.com/davidfowl/dotnetcli-aspnet5/tree/master/HelloMvc) after removing that package from project.json

[davidfowl]

So it looks like we're going to need XDocument as well:

FileNotFoundException: Could not load file or assembly 'System.Xml.XDocument, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

It's all JSON.NET. Hopefully it'll all go away once we're netstandard and JSON.NET is updated to have dependencies listed.

When you release RC2 and the tools are there, I'll release a version with netstandard 😁

Sure I'm just looking at what's blowing up right now
