Fix iTunes Connect error reg. resource bundle

Xcode 7 shows an error when uploading an app to iTunes Connect due to a bug in the Info.plist of the resource bundle. The info.plist shouldn't contain a `CFBundleExecutable` value and the `CFBundlePackageType` should be `BNDL`.

Also removed other non needed entries.
