block: add bdrv_open_backing_file
Mirroring runs without the backing file so that it can be copied outside
QEMU. However, we need to add it at the time the job is completed and
QEMU switches to the target. Factor out the common bits of opening an
image and completing a mirroring operation.
The new function does not assume that the file is closed immediately after
it returns failure, so it keeps the BDRV_O_NO_BACKING flag up-to-date.
