fix initialization of DEB_VENDOR for derivatives

[Jon Boden]

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.

The attachment "libreoffice.diff" seems to be a patch. If it isn't, please remove the "patch" flag from the attachment, remove the "patch" tag, and if you are a member of the ~ubuntu-reviewers, unsubscribe the team.

If you fork Ubuntu packages, you have to fork them properly: This stuff needs to happen downstream at ubuntuBSD anyway.
Note that the Ubuntu customization is NOT to be used for ubuntuBSD, there are big warnings about that e.g. GOOGLEAPI_APIKEY_UBUNTU, so compiling the with the Ubuntu config would be wrong anyway.

Finally, note that properly forked downstreams actually might depend on the Ubuntu specific to be applied for them and this "fix" would break them.
