Can you add a comment about *why* this is a dependency (the isolate needs this,
even if test_support doesn't actually use this).

And, also, we should figure out if there's a similar place we should add in a
dependency for xvfb.py. Currently mb adds it for everything on configs that use
x11, but perhaps that should be a dependency of something in //ui or something.
