Skip /Perl6/ modules

[ranguard]

No point trying to smoke Perl6 just yet!

Such as:

http://matrix.cpantesters.org/?dist=IO-Socket-SSL%200.000.001

See also:

https://github.com/perl6modules/dists-uploaded-to-cpan/issues/1

I'll try work on this when I get a moment, but wanted to document the intention incase others have comments
