And another change should be to wrap the code in
tools/hotplug/Linux/Makefile:install-initd in a ifneq($(CONFIG_SYSTEMD),y)
to have either one or the other. But that would break the support for
one package for both sysv and systemd.

Up to now I have not checked how systemd support works in real life.
Looks like systemd has trouble to decide if sysv or service files should
be used. Or the OP has to enable all service files manually.
