[bug#55659] [PATCH 1/2] services: ddclient: Fix extra-options serialization.

[Attila Lendvai]

Prior to this fix it has serialized "extra-options=..." into the ddclient.conf
file.

* gnu/services/dns.scm (serialize-field): Special case for extra-options.
(serialize-extra-options): Deleted unused function.
(ddclient-configuration): Change the type of the extra-options field to be a
string, and emit it verbatime into the ddclient.conf file. Change
docstring accordingly.
---

please note that even though this does fix an issue, i have abandoned
further work on ddclient. so, this is an improvement indeed, but i
suspect that this does not fully fix ddclient. looks like the conf
file format is different than what the current code emits.

the next patch updates ddclient to an RC2 of the next version,
which will be a major upgrade.
