conf: Support disk source formatting without needing a virDomainDiskDefPtr

Browse Source 
The <source> element formatting function was expecting a
virDomainDiskDefPtr to store the data. As snapshots are not using this
data structure to hold the data, we need to add an internal function
which splits out individual fields separately.
