Correctly derive ABI for apps on adopted media.

There was a bug causing PackageManager to think apps on adopted media
were actually in an ASEC, causing it to skip ABI derivation.  This
change fixes the issue by copying the volume UUID into place early
in the scanning process.

Also fixes two places where we had incorrectly been including apps
on adopted media; switched them to check only for ASECs.
