[OSSTEST PATCH 9/9] NTP servers: Work around Debian's failure to honour preseed

[Ian Jackson <ian.jackson@eu.citrix.com>]

Setting clock-setup/ntp-server is not sufficient: it only takes effect
in the installer (!)

I have reported this as Debian #778564.  In the meantime we should
work around it for current releases (including jessie, which is
frozen).

For later releases, the new ntp.conf editing code arranges to bomb out
if we have an NTP server configured and find it hasn't been honoured
during the install.
