okay, I lied, I think this should go in //chrome/BUILD.gn since that's the only
place it's used, and then you can share the outfile constant.

Done.

nit: for no good reason, convention is to use build-relative paths rather than
absolute ones by passing  root_build_dir as the second arg here.

Done.

You can just hardcode this as: --out-dir=.
