dh_installinit --name <service> is for forcing install debian/*.service
and debian/*.default that does not matches with package name.
And if we have subpackages, packager has responsibility to rename
debian/*.service to debian/<subpackage>.*service.
However, we currently mistakenly running
dh_installinit --name scylla-node-exporter for
debian/scylla-node-exporeter.service,
the packaging system tries to find destination package for the .service,
and does not find subpackage name on it, so it will pick first
subpackage ordered by name, scylla-conf.
To solve the issue, we just need to run dh_installinit without --name
when $product == 'scylla'.
