CMake linter default line length differs depending on invocation

[emersonknapp]

• Using ament_lint_cmake entrypoing from shell - defaults to 80 chars from https://github.com/ament/ament_lint/blob/master/ament_lint_cmake/ament_lint_cmake/cmakelint.py#L87
• Using ament_cmake_lint_cmake to call ament_lint_cmake() from CMakeLists.txt - it defaults to 140 chars because of https://github.com/ament/ament_lint/blob/master/ament_cmake_lint_cmake/cmake/ament_lint_cmake.cmake#L44

This means that, given no external configurations, calling the same tool two ways can have different results. Not sure what the best way to resolve this is - my first thought is to add a default=140 to the ArgumentParser - and to remove the CMake default to avoid duplicate information

That sounds good to me. If you want to open a PR for this, feel free to @ me as a reviewer.
