bind: remove -r option from rndc-confgen in initscript
The -r option has been removed from rndc-confgen since bind 9.13[1].
Fix the bind startup error:
$ /etc/init.d/bind start
Starting domain name service: namedrndc-confgen: The -r option has been deprecated.
chmod: cannot access '/etc/bind/rndc.key': No such file or directory
