Bug#648954: [patch] doc-base Conflicts are insufficient

tag 648954 patch
thanks

Hello Niko, Dominic,

we still got quite a lot of upgrade failures with -6
(https://launchpad.net/bugs/902553).

-6 adds a Conflicts: doc-base (<< 0.10.3) to perl-base. This correctly
prevents unpacking of perl-base 5.14 and breaking the doc-base
trigger. However, in above LP bug we see

dpkg: error processing doc-base (--unpack):

At this point neither doc-base nor perl-base was unpacked (which is
what -5 and -6 fixed). Full logs are in the LP bug and its duplicates,
but above is the gist of it.

So we need to Conflicts: harder. Patch attached.

Thanks for considering,

Martin
