Always populate the ApplicationInfo object

While scanning system apps, we abort package/application info setup
if an app on /system is not a higher version than an upgrade on /data.
Instead, we need to still fully populate these objects because they
can be retrievd using the MATCH_FACTORY_ONLY flag.
