Fix compressed stubs

Whenever the stub package is uninstalled from /data, we now
install the compressed version from the system image.

Disabling a package still does not remove any version on /data.
This means that a compressed package may be un-updated, yet
disabled and it will continue to consume space on /data. To
clear /data completely, disable the application and then uninstall.
