[PATCH v2 1/7] virDomainCapsEnumFormat: Switch to virXMLFormatElement()

[Michal Privoznik <mprivozn@xxxxxxxxxx>]

We are formatting <enum/> element and its children using
virBufferAddLit(), virBufferAsprintf(), virBufferAdjustIndent(),
etc. Well, we can avoid that when switching to
virXMLFormatElement().
