The intention was that systemd only needs systemd-hwdb at runtime and not
at build-time. So we have the 'if RUNTIME' here. And systemd-hwdb needs
host-systemd, so it selects it.
The problem is in the way 'if RUNTIME' is implemented:
kconfig runs with RUNTIME. Since systemd-hwdb has no prompt, it is disabled
entirely so the build-time dependency systemd-hwdb -> host-systemd is not
added :-/.
I'll think about this some more, but I think removing the 'if RUNTIME' is
the best solution. I'll fix it.
