systemd: Package systemd-hwdb-update.service into udev

Currently, this unit is packaged into udev-hwdb which then adds it as rdep
instead of rrecommends to systemd itself, this meant that even if we
added udev-hwdb to BAD_RECOMMENDATIONS, it would not be respected since
its a rdep, therefore move the service unit file into udev package
instead, this decouples the hard runtime dependency and restores the bad
recommendations expectations
