profiles: unmask newest CPAN Test-Simple

Unfortunately, the core version of Test-Simple/Test::More has one or
more annoying bug, that leads to it breaking things like Archive-Zip's
test suite.

Thus, a newer version is needed in tree if you have Perl 5.26 :/

Sadly, this will probably create an upgrade crisis down the chain for
everyone with a perl-core leaf, but at least, gentoo-perl-helpers fixes
that problem.
