Move persistent data to /data/vendor.

Browse Source 
Widevine persistent data is stored in /data/mediadrm, HALs
are not allowed to access files in /data. Move persistent
data to /data/vendor/mediadrm/widevine for older devices,
and persistent data will not be saved under /data/vendor.

Test: Play Movies & Tv, Netflix
