Perhaps the simplest, more natural way to fix this would be to do the
following:

1. Revert to use simple strings for the user/group, with their types to
maybe-string.

2. When the fields are specified, it's assumed that their corresponding
user/group already exist, as done for other services.  When unspecified,
then the service takes care to extend the user-accounts service with the
mpd user/group.

This means we do not have to expose user-accounts at the
<mpd-configuration>, which is not the right place for that anyway; it's
already exposed via the users/groups fields of the <operating-system>
record.

That's much easier to reason with, for both humans and the code, in my
opinion.
