virtual/perl-Test-Simple: remove dev-lang/perl fallback for perl-5.20

virtual/perl-Test-Simple: remove dev-lang/perl fallback for perl-5.20

This is part of the fix of bug #584238. This bump removes
dev-lang/perl-5.22 and dev-lang/perl-5.24 from the alternatives list for
people using this virtual.

If you're upgrading to perl-5.22, you should upgrade to
virtual/perl-Test-Simple-1.1.14_p522 at the same time, which will excise
perl-core/* instead of pulling perl-core/*

Keywords DROPPED: ~arm ~alpha , because they were previously only
stabilized because dev-lang/perl was stable for those keywords.

However, perl-core/Test-Simple-1.1.14 is not stable, so this can't be an
alternative and stay stable.

But virtual/perl-Test-Simple-1.1.14_p522 is already "stable" for ~arm
and ~alpha, so people on stable will move directly there.
