[PATCH 11/11] conf: Separate out virDomainClockDef formatting

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

Currently, virDomainClockDef is formatted inside
virDomainDefFormatInternalSetRootName() which is already long
enough. Move the code into a new function
(virDomainClockDefFormat()) and make the code use
virXMLFormatElement() while at it.
