[PATCH v1 5/5] debian: add generic rule file

[Enrico Weigelt, metux IT consult]

Adding a generic debian rule file, so we can build the directly
via usual Debian package build tools (eg. git-buildpackage,
dck-buildpackage, etc). It expects the .config file already
placed in the source tree.

The rule file contains a rule for creating debian/control and
other metadata - this is done similar to the 'deb-pkg' make rule,
scripts/packaging/mkdebian.
