Code review comment for ~ahasenack/ubuntu/+source/bind9:mantic-dyndb-dep8-fixes

I now pushed a different set of changes, please take another look.

These fix the i386 problem, and I also included a small fix that was not affecting the test, but is addressing something I had wrong in the ldap_bind9_dn ldap entry.

The tests finished, and here is the summary:

a) non-i386:

594s autopkgtest [16:51:38]: @@@@@@@@@@@@@@@@@@@@ summary
594s simpletest PASS
594s validation FLAKY non-zero exit status 1
594s zonetest PASS
594s dyndb-ldap PASS

b) i386:

260s autopkgtest [16:46:05]: @@@@@@@@@@@@@@@@@@@@ summary
260s dyndb-ldap SKIP Test declares architecture as not supported: i386
260s simpletest PASS
260s validation FLAKY non-zero exit status 1
260s zonetest PASS

The i386 exclusion will have to be part of our delta I'm afraid :/
