Ensure packages on adopted media do not move when updated

Packages not installed with PackageInstaller.Session that
are moved to adopted storage via android storage settings
will get moved back to private internal storage when the
package is later updated.  This causes the app to lose
it's data (and leaves the data dir dangling on the original
adopted location).

play market installs do not have this problem (because
they use an installer session) but pretty much every other
app install route does.  eg adb install and other app stores.
