Fingerprint data is now stored in one of two ways depending on the

shipping API version:

For devices shipped before Android P nothing changes, data
is stored under /data/system/users/<user-id>/fpdata/...

Devices shipped from now on will instead store
fingerprint data under /data/vendor_de/<user-id>/fpdata.

Support for /data/vendor_de and /data/vendor_ce has been added to vold.
