Subject: [PATCH] Remove `ENV['TRAVIS']`

Rather than replace `ENV['TRAVIS']` with `ENV['CI']`, I think we can
remove this condition because `ENV['TRAVIS']` is not valid at Buildkite
then Rails CI has been running with `PROCESS_COUNT` about 9 month
since this https://github.com/rails/rails/commit/e485c14a3ee29ee486324a96545abf964d428101
