Add Dockerfile for image using SCD

You can probably just copy the current Dockerfile and just change the second (actual, non-builder) image a bit.

Maybe the SCD works not only on microsoft/dotnet:1.1-runtime-deps, but on smaller images like Alpine as well? That would be an advantage for using the SCD in a Docker image.

See https://github.com/dotnet/core/blob/master/Documentation/prereqs.md for dependencies that are needed for running SCDs.

Regarding Alpine, see dotnet/dotnet-docker#22

Alpine seems to be a valid RID already, but not sure in which release or if fully supported or not: https://github.com/dotnet/corefx/blob/c6dbe361680efd21a20fdb8def01936b1031011c/pkg/Microsoft.NETCore.Platforms/runtime.json#L29

Also note: Even when an SCD in an Alpine image is small, the .NET Core runtime Alpine image is probably small as well. Check the difference to see if it's worth the effort.

A .NET Core Alpine image is now available: https://www.hanselman.com/blog/TryingOutNewNETCoreAlpineDockerImages.aspx
