Don't sort mck->generators in Test::Kwalitee

... as generators are already ordered (with sub order {} in Module::CPANTS::Kwalitee::*)

Some of the metrics (proper_libs etc) depend on the result of other generators/analyzers. Sorting in Test::Kwalitee may (and actually do) break this dependency. For example, no_index in (MY)META.yml will be ignored, and some of the metrics may fail because of the files that should be ignored.
