moving privdata to privdata.joey (for joeyconfig branch only)

This will be reverted on master. This way, my ongoing development on my
joeyconfig branch, including privdata changes, won't result in changes
being merged into the privdata/ dir on master. Such changes can cause
problems for other propellor users, who can get conflicts in their own
privdata when merging from master.
