services: configuration: Allow specifying a custom serializer.

In some cases, rather than globally disabling serialization, it may be more
appropriate to disable or otherwise alter the serialization procedure of a
specific field.  In large module, multiple configurations may also exist that
would need to alter the default serialization procedure, which is named after
the field type.  Being able to specify a per-field serialization procedure
provides more flexibility.

* gnu/services/configuration.scm (define-configuration): Add an optional
pattern variable to allow specifying a custom serialization procedure.
(define-configuration-helper) <field-serializer>: Use it to transform the
syntax.
(empty-serializer): New procedure.
(serialize-package): Alias to ‘empty-serializer’.
