Debian packaging improvement (#459)

* debian: use dh-sequence-python3

* d/control: add missed gir packages dependencies to cinnamon-screensaver

including the ones that are virtual for now

* d/control: Remove unnecessary constraints

when version in oldstable is major is not needed anymore

* switch to debhelper-compat and compat 13

also remove from d/rules things that are now default

* debian: remove file of a package that was removed

* d/control: remove old breaks/replaces

are older that Debian oldstable and previous ubuntu LTS so are not
needed anymore and without risk
