qemuBlockGetBackingStoreString: Add extra wrapping object to JSON strings QEMU requires an extra wrapper object where only the "file" member is populated.

We did the same in qemuDiskSourceGetProps for the old-school JSON usage with -drive but forgot to adopt this for -blockdev. https://bugzilla.redhat.com/show_bug.cgi?id=1804617 Signed-off-by: Peter Krempa <pkrempa@redhat.com> Reviewed-by: Michal Privoznik <mprivozn@redhat.com> 2020-03-23 15:09:31 +00:00			`"backing-file": "json:{\"file\":{\"driver\":\"raw\",\"offset\":1234,\"size\":5768,\"file\":{\"driver\":\"file\",\"filename\":\"/var/lib/libvirt/images/i.qcow2\"}}}",`
