Add a pattern showing using compiled dependencies for ruby

[joyofhex]

Issue #, if available:

Description of changes: This adds a pattern that can be used when you need to use a gem with native extensions that also require shared libraries to be available at runtime. To do so we build a custom build container containing the needed libraries, then create a lambda layer that has those libraries present. Finally we build the application and create a .zip archive.
