perl: fix Perl5 module builds

This patch fixes some issues in classes providing cpan module build support:

* add support even for xs modules with more than 3 levels as
  B::Hooks::End::Of::Scope or Math::Random::ISAAC::XS
* correct handling of Module::Build (as far as stolen from pkgsrc
  and my humble knowledge)
* configure to install to vendor_libs as default, even when
  inherited do_install remains unused (overwritten do_install)
