package.bbclass: Detect duplicates in PACKAGES properly.

* Fix bug which caused non-detection.
* Make visible error message for such condition.
* But still recover and continue for now, while we don't
have all occurances fixed in metadata. Note that while
content of the package will be ok, metadata can be wrong.
So, recover behavior should not be relied upon, this going to
be fatal condition later.
