Switch to usage with dh-sequence-dkms
Since Debian/bookworm dh-dkms (debhelper addon for the Dynamic Kernel Module System (DKMS)) is available with its virtual dh-sequence-dkms package. This allows us to get rid of manual packaging work in maintainer scripts and debian/rules.
Patch provided by Andreas Beckmann in #1030227, adjusted to keep delta to upstream as small as possible.
Thanks: Andreas Beckmann anbe@debian.org for bug report and initial patch
