dns/resolved: use nm_utils_hash_to_array_with_buffer() in NMDnsSystemdResolved's update()

Browse Source 
We copy the content of the hash table to an array, so that we can sort
the entries and they have a defined order.

We are not only interested in the keys, but the keys and the values.
Hence, use nm_utils_hash_to_array_with_buffer() which gives both at
the same time.
