docs(perl-security): drop nonexistent perlcritic policies

Perl::Critic has no InputOutput::RequireThreeArgOpen or
Modules::RequireTaintChecking policy. perlcritic warns that they are
not installed and ignores them. Two-arg open is already covered by
InputOutput::ProhibitTwoArgOpen in the same profile. Regenerated pi/core.
