Force ordering of :yoga/:yogaForDebug

Summary:
Due to testutil depending on :yoga, we are always linking against both
:yoga and :yogaForDebug in tests. This is only working right now due to luck in
how Buck orders the link line. Adding a dependency is silly but it enforces
that Buck maintain the ordering that we currently have even when it changes how
it does its traversal.
