Get rid of t/99-kwalitee.t New versions started to throw warnings if specific environment variables are not set.

Replace $] by "$]" An old bug could cause $] to be initialized to a wrong decimal value. Since its stringified value was always right, we use it instead. Occurences of $^V were also replaced by $].
