Ubuntu packaging: add support for better changelog tracking

This now assumes that a running changelog is maintained in
src/debian.changelog, i.e., at the same level as the subsurface tree; the
organization now should look like this:

src/debian.changelog
src/subsurface                 # subsurface git checkout
src/subsurface/libdivecomputer # libdivecomputer git Subsurface-xx branch
src/subsurface/marble-source   # marble git Subsurface-xx branch
src/subsurface/libgit2         # libgit2 git checkout

Instead of running dh_make to create all new debian build files, we add the
necessary files in our script.
