Match strict equivalent modules from Perl::Critic

[ferki]

This is an attempt to fix #20 by reusing the list of strict equivalent modules from Perl::Critic::Utils::Constants.

Since Test2::V0 is not included there (yet?), I've also added an explicit test case for it to make sure it remain compatible with the previous list of modules on this side.

I hope this idea is useful; please review and merge, or let me know how to improve it further.

@ferki Thank you for your works! It is indeed a good idea to avoid duplicate works, especially when the same list is already defined in Perl::Critic. :)
