Perl 5.20.0 intel 204b

the existing ictce/5.5.0 easyconfig for Perl v5.20.0 has `1.04` here; is this version bump strictly required?

also, additional Perl modules are added in here

we like to keep easyconfigs in sync across toolchains, so add the extra Perl modules in the other easyconfigs for Perl v5.20.0 too
