cooker: ensure that the cache sync completes 

Without explicitly joining the thread, it's possible for the process to end
(e.g. after a bitbake -p) and kill off the thread without waiting for it to
exit cleanly.  So, register the thread join with atexit.

(Bitbake rev: 97ce57e6f860d3e6f34cc7a603ed1eeac4f423d3)
