lint.sh script fails for engine files. Example: https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket.appspot.com/8874483205899836240/+/steps/lint_test/0/stdout

We disabled the script for now.

(1) We should either change the script or fix the code.
(2) We should re-enable the script on LUCI engine and web_engine recipes.
