insane: add check for perllocal.pod

perlocal.pod is an index file of locally installed modules and so shouldn't be
installed by any distribution packages.  cpan.bbclass already sets NO_PERLOCAL
to stop this file being generated by most Perl recipes, but if a recipe is using
MakeMaker directly (such as rrdtool) then they might not be doing this
correctly.

To avoid multiple packages shipping this file and then failing to install
together, add a QA test to check if this file exists and by default emit an
error if it does.
