Does the path now need to point to src/third_party/catapult/devil? Right now it
points to src/build/android.

[jbudorick, 2016/07/07 17:12:03]

devil_chromium takes care of that part. I could change it to point to
third_party/catapult/devil, but it isn't strictly necessary for this CL and
involves broader changes AFAICT.
