d855: Address 'LOCAL_MODULE_TAGS := eng debug' deprecation.

Newer AOSP deprecates LOCAL_MODULE_TAGS := eng debug.
We now remove that and instead add the package to
PRODUCT_PACKAGES_ENG or PRODUCT_PACKAGES_DEBUG as applicable.

To ensure that we don't miss out on any package during this switch,
we add these explicitly, even though it might have been already
added under PRODUCT_PACKAGES at some other location.
