Update debhelper (#13594)

* Update debian packaging to debhelper version 12

Don't call dh_installinit anymore, because it has been deprecated, and use
dh_installsystemd instead of dh_systemd_enable for the same reason.

Signed-off-by: Jörg Behrmann <behrmann@physik.fu-berlin.de>

* Drop preinst script

It was used for reasons of interactions of dh_systemd_start and dh_installinit,
which have both be deprecated

* Drop /etc/default file

It was no longer being installed.

* Remove debian/compat file

This is managed by the control file nowadays
