Build F-Droid Privileged Extension

* This privileged system app (aka /system/priv-app)
  acts as a proxy to the actual F-Droid app to install and uninstall
  packages without having to enable unknown sources.
* Works with the F-Droid official app (signed with official keys)
  installed on either system or data.
