I guess this file doesn't exist, and gyp doesn't complain about excluding it.

Yes, looks like the file itself was moved in
https://codereview.chromium.org/11359147 - I suppose (but don't know gyp well
enough) that excluding a file that doesn't exist is equivalent to excluding a
file that might have been already excluded by another rule. Anyway, seems like a
good time to fix this up.
