- rc.d script now generates the unbound-control keys if they don't exist
and the sample config file is patched to enable this, various rc.d/unbound
actions depend on this, pointed out/ok aja@
Previously if unbound-control was used to restart the daemon, further
use of /etc/rc.d/unbound would no longer match the process title.
