Fix CPAN{,-Meta{,-YAML}} and related sub-packages
    
    - Parse-CPAN-Meta explicitly requires CPAN::Meta::YAML and JSON::PP
    - Exclude CPAN::Meta* from CPAN sub-package
    - Don't try to normalize CPAN-Meta, JSON-PP, and Parse-CPAN-Meta versions;
      their dual-life packages aren't and have much higher numbers already
