Bug#589816: dh-make-perl: does not recognize Artistic 2.0

[Ansgar Burchardt]

Package: dh-make-perl
Version: 0.68-1
Severity: normal
Tags: upstream

dh-make-perl does not recognize the license statement inserted by
Dist::Zilla for the Artistic-2.0 license.  Instead it thinks the license
used is the old Artistic license as used by perl.

Example: MooseX-FollowPBP-0.04 from CPAN.  The following statement can
be found in lib/MooseX/FollowPBP.pm:

  This software is Copyright (c) 2010 by Dave Rolsky.

  This is free software, licensed under:

    The Artistic License 2.0

META.(json|yml) also include "artistic_2" in the "license" field.

Regards,
Ansgar
