conf: Extract host XML formatting from virCapabilitiesFormatXML
Let's extract out the <host> code into it's own method/helper. NB: One minor change between the two is usage of "buf" instead of "&buf" in the new code since we pass the address of &buf to the helper. Signed-off-by: John Ferlan <jferlan@redhat.com> ACKed-by: Michal Privoznik <mprivozn@redhat.com>
