Remove dead archives for p5p
Remove dead archives for p5p

via Andy Lester
There are three archive links, but only one is up-to-date:
http://www.mail-archive.com/perl5-porters@perl.org/ only has messages as recent as 2005
http://grokbase.com/g/perl/perl5-porters seems to have stopped archiving back in June.

[perl #129970] Ancient links to remove on https://lists.perl.org/list/perl5-porters.html
