services: zabbix: Support gexps in configuration serializer.

This makes it possible to do e.g. (include-files (list (local-file "foo.conf"))).

* gnu/services/monitoring.scm (serialize-field, serialize-list,
serialize-include-files, serialize-extra-options): Rewrite as gexps.
(zabbix-server-config-file, zabbix-agent-config-file): Simplify builders by
using FORMAT.
