Include the framebuffer lib with the vulkan loader

Adding this dependency to the fuchsia vulkan loader allows the
framebuffer library to serve as the binary-stable display API. Once the
display controller fidl API is stable, it will provide a stable,
statically-linkable display API, at which point this implicitly
available API can be removed.
