Given the presence of "WidevineCdm" below (and need for both a ECK and WV path),
I wonder if this should be:
.../WidevineCdm/<(platform_specific_path)

Yes for the future. For now, the tricky part is that on linux/cros, we are not
even using the WidevineCdm part, so this will not work.

We could have a follow-up CL later to move linux/cros CDMs to WidevineCdm
folder, then we can do what you suggested.
