Cop/RedirectWithStatus: Stop checking location programmatically

What does this MR do and why?

Use RuboCop's Include directive instead. With this the cop is now also inspecting controller concerns (not ending with _controller.rb).

This commit also refactors to cop to use the RESTRICT_ON_SEND optimization and improves code coverage.

Test on gitlab-org/gitlab

Because we now also check controller concerns we got us two offenses when inspecting gitlab-org/gitlab.
