fix typo so package manifest is used and permissions are copied to the APK

@jhugman: you and I ended up making similar changes this evening! I got icons working in very much the same way (except that I used the *temp* module to create a temporary directory to extract the files to).

But one of your changes broke permissions. Here's the typo fix that corrects the problem.

(It didn't hork icons because those are in both manifests, so once the builder started looking for them in the right place, it found them from their references in the minifest.)
