Migrate ss data to both of system/admin user db

Migrate ss data to both of system/admin user db

Some services changed from system to user and they should handle
migrated data and newly saved data differently by changing owner
label because user service cannot save to system db

To use key-manager uniformly by client who is in the case above,
migrated data is going to saved on both of system and admin user
(owner : 5001) db with owner "/User" because user service's smack label
is "User"
