I think this is not necessary. Right?

This fixes the analyze step failure from the prior patch set:
https://build.chromium.org/p/tryserver.chromium.linux/builders/linux_chromium...
ERROR at //skia/public/interfaces/bitmap_skbitmap_struct_traits.h:8:11: Include
not allowed.
#include "mojo/public/cpp/bindings/array_traits.h"
          ^--------------------------------------
It is not in any dependency of
  //skia/public/interfaces:interfaces_cpp_sources
The include file is in the target(s):
  //mojo/public/cpp/bindings:bindings
