Zbigniew Jędrzejewski-Szmek e71074f761 various: convert "services" to option macros
Here we have the unusual situation that the option list is
conditionalized. I thought about embedding some "tag" information in
individual options to allow the options to be filtered by some arbitrary
conditions. But it seems that using groups works quite well. It wouldn't
scale well if there was a lot more options and conditions, but for the
current set it's good enough.

For options that are not supported in a given service, we print a custom
message ("This service does not support [this] option"), instead of the
generic "Unknown option …". I think this is actually better: we don't
have to pretent that we don't know about the option, and can directly
say that the it's a valid option in general but this service does not
support it (yet).

This converts systemd-homed, systemd-hostnamed, systemd-importd,
systemd-localed, systemd-logind, systemd-machined, systemd-networkd,
systemd-portabled, systemd-resolved, systemd-sysupdated,
systemd-timedated, and systemd-timesyncd.

When we add introspection of the option data, we'll somehow have to deal
with conditionalization. But let's cross that bridge when we need to.
