man: describe all the changes to ukify

As in mkosi(1), let's describe the config file and commandline options
together. This is nice for us, because we don't need to duplicate descriptions
and we're less likely to forget to update one place or the other. This is also
nice for users, because they can easily figure out what can be configured
where.

The options are now ordered by config file section.

--summary was not described before.

More examples are added.
