app-admin/perl-cleaner: rework portage/pkgcore dependencies

This gives us a runtime-only USE flag but it's better than the
alternative which regularly leads to at least portage-utils
being depcleaned because pkgcore is installed, and then
perl-cleaner being broken at runtime because it doesn't
actually detect which to use based on available tools.
