perl: Invert perlbase-essential/perlbase-config circular dependency solution

perlbase-essential and perlbase-config depend on functionality from
each other. Previously, this was solved by just making perlbase-config depend
on perlbase-essential.
However, since a simple "use lib" is enough to trigger pulling in Config, this
approach doesn't seem to make much sense. So let's just make perlbase-essential
depend on perlbase-config instead.
This pulls in perlbase-config as a dependency to pretty much every Perl package,
so in the future we might want to just merge Config into perlbase-essential.

Thanks to Robert Högberg for spotting this.
