build system: target to make a Debian snapshot package.

Currently this builds a native package, but since the source package
is throw away, it should not matter too much, except for the extra
warnings from lintian.

The extra +1 is so that if $(VERSION) is the same as the last released
version (for example outside a git repo) then the versions still order
correctly.
