[libvirt] [PATCH v5 3/9] virstoragefile: Add virStorageSourceSetBackingStore

As explained for virStorageSourceGetBackingStore, quorum allows
multiple backing store, this make the operation to set bs complex
because we have to check if the backingStore is used as an array
or a pointer, and set it differently in both case.

In order to help the manipulation of backing store, I've added a
function virStorageSourceSetBackingStore.

For now virStorageSourceSetBackingStore don't handle the case where
we have more than one backing store in virStorageSource.
