Bug#829379: fix initialization of DEB_VENDOR for derivatives

[Jon Boden <jon@ubuntubsd.org>]

Package: libreoffice
Version: 5.2.0~rc1-1
Tags: patch

Hi

debian/rules only supports two values for DEB_VENDOR: Debian and Ubuntu. As derivative distributions put other values in this variable, libreoffice cannot be built there.

With this patch DEB_VENDOR is always initialized to either Debian or Ubuntu depending on which the host distribution derives from.

This problem was found when trying to build libreoffice on ubuntuBSD but is likely to affect other derivative distributions.
