RT#80225: Test::CPAN::Meta::YAML::Version 0.21 compat

From https://rt.cpan.org/Ticket/Display.html?id=80225

When Test-CPAN-Meta-YAML was upgraded to version 0.21 (August 12 2012)
there was an interface change in Test::CPAN::Meta::YAML::Version. The
actual YAML data, formerly passed as key 'yaml', is now passed as key
'data'.

The attached patches update Module::CPANTS::Kwalitee::MetaYAML
to track this change, and Build.PL and Makefile.PL to require
Test::CPAN::Meta::YAML::Version version 0.21. They have been tested
successfully under Perls 5.14.3, 5.16.1, and 5.17.4.
