MAAS post-inst script can create duplicate lines in named.conf.local

[Kellen Renshaw]

The sed line in line 8 of debian/maas-dns.postinst can cause creation of a duplicate line in named.conf.local since it doesn't check case. This happened on a 2.0 to 2.2 upgrade.

Bind read the configuration twice and failed to start.

The resulting config in named.conf.local:
//
// Do any local configuration here
//

// Consider adding the 1918 zones here, if they are not used in your
// organization
//include "/etc/bind/zones.rfc1918";

Include "/etc/bind/maas/named.conf.maas";
include "/etc/bind/maas/named.conf.maas";

####
Deleting one of the lines and restarting Bind works to correct the issue.
