block/dmg: set virtual size to a non-zero value
Right now the virtual size is always reported as zero which makes it impossible to convert between formats. After this patch, the number of sectors will be read from the trailer ("koly" block). To verify the behavior, the output of `dmg2img foo.dmg foo.img` was compared against `qemu-img convert -f dmg -O raw foo.dmg foo.raw`. The tests showed that the file contents are exactly the same, except that QEMU creates a slightly larger file (it matches the total sectors count).
