cpan-base.bbclass: Update the perl depenedencies: (from OE)

* For native modules DEPEND on perl-native and for others DEPEND on perl
  (which in turn depends on perl-native) rather then always depending on
  both perl and perl-native.
* Only RDEPEND for non-native modules rather then both native and non-native.

These changes are to allow you to build native modules without have to build
perl. Previously the dependencies would result in perl being built even
though it didn't actually need to. Thanks to hrw for pointing out what was
happening here.
