qemu-img: Change img_rebase() to be byte-based

In the continuing quest to make more things byte-based, change
the internal iteration of img_rebase().  We can finally drop the
TODO assertion added earlier, now that the entire algorithm is
byte-based and no longer has to shift from bytes to sectors.

Most of the change is mechanical ('num_sectors' becomes 'size',
'sector' becomes 'offset', 'n' goes from sectors to bytes); some
of it is also a cleanup (use of MIN() instead of open-coding,
loss of variable 'count' added earlier in commit d6a644bb).
