Bind configuration now includes 2 snippet config files, in
/etc/named/ipa-ext.conf and /etc/named/ipa-options-ext.conf
When a test needs to disable dnssec-validation, it needs to edit
the snippet ipa-options-ext.conf instead of /etc/named.conf.
This commit fixes the method tasks.disable_dnssec_validation so that it
correctly updates the snippet.
