qemu-img: Allow rebase with no input base
Currently, without -u, you cannot add a backing file to an image when it
currently has none:
$ qemu-img rebase -b base.qcow2 foo.qcow2
qemu-img: Could not open old backing file '': The 'file' block driver
requires a file name
It is really simple to allow this, though (effectively by setting
old_backing_size to 0), so this patch does just that.
