iotests: Test backup job with two guest writes

Perform two guest writes to not yet backed up areas of an image, where
the former touches an inner area of the latter.

Before HEAD^, copy offloading broke this in two ways:
(1) The target image differs from the reference image (what the source
was when the backup started).
(2) But you will not see that in the failing output, because the job
offset is reported as being greater than the job length. This is
because one cluster is copied twice, and thus accounted for twice,
but of course the job length does not increase.

iotests: Add regresion test case for write notifier assertion failure

The idea is to let the top level bs have a big request alignment with
blkdebug, so that the aio_write request issued from monitor will be
serialised. This tests that QEMU doesn't crash upon the read request
from the backup job's write notifier, which is a very special case of
"reentrant" request.
