build-system: update Ubuntu/Debian package script

This cleans up a lot of the ancient mess in that file.

It's still confusingly usable to push sources to OBS as well (but that's now
hidden behind an option) and it is still somewhat custom-made for me, but it
should be much easier to reuse for others now.

In addition to Subsurface and libdivecomputer we are inclooding the googlemaps
sources and libgit2 1.0.0 sources. Bionic is the only remaining distro that we
support that doesn't have a new enough version of libgit2 (0.26 is the minimum
we expect), but since we are linking statically against it, maybe it's best to
simply force all of these builds to include libgit2 1.0.0.

Handling of the debian/* files in the script has been changed quite a bit to
make it easier for others to create a working setup. It now updates all of the
files with the exception of the changelog files from the sources we are
building from. I am hoping that this will be a not-so-subtle incentive for me
to keep the bundled versions up to date.

Since we no longer do beta releases, I removed that part from the file.
