Revert "Remove previously added missing brace/bracket commas"

The unofficial Airbnb config (eslint-config-airbnb-es5) previously
thought this to be an error and so it was removed. The official Airbnb
config (airbnb/legacy) now works just like the ES6 config (airbnb).

Fixes ESLint comma-dangle errors using airbnb/legacy config.

This reverts commit 49d58d98f5866bb9ccc9069a16d131486f04bba2.
