networkctl: if there's no data from networkd about an iface show as "unmanaged"

After all, if we know that an interface exists but networkd did not store any
info about it, then it's definitely unmanaged by it.

(Note that we add this fix-up to networkctl, and not to sd-network, simply
because a missing file might also be result of the interface not existing.)
