[PATCH 6/6] Hack up distcheck for publican

[Peter Hutterer]

Publican requires a read-write source tree, see
http://bugzilla.redhat.com/show_bug.cgi?id=798484

And it currently cannot build out-of-tree, so we need to copy the sources
into the _build tree and generate Protocol.xml into that tree too (we'd have
to do this anyway since automake creates a read-only source tree, so we
can't just link).

Gaetan, if you have any better suggestions I'd love to hear them.
