ACLs are unusable with allow_transfer

[damluk]

The following beaker test fails on Debian 10 and probably other distros, even though it might encode a desirable setup:

diff --git a/spec/acceptance/dns_spec.rb b/spec/acceptance/dns_spec.rb
index 50f6729..8ddc748 100644

   end

The error is due to named-checkconf:

Error: Execution of '/usr/sbin/named-checkconf /etc/bind/zones.conf20200501-1763-1xd9g1x' returned 1: /etc/bind/zones.conf20200501-1763-1xd9g1x:7: undefined ACL 'trusted'

Interestingly there are other ACL-capable clauses that do not care about undefinedness in the same config file.

The best solution I can come up with, is to place acl, view and zone definitions into the same config file.

Looks like this problem is not limited to Debian 10.
