qemu-iotests: add 053 unaligned compressed image size test 



Test that qemu-img convert -c works when input image length is not a
multiple of the cluster size.

Previously an error message would be produced:

  qemu-img: error while compressing sector 0: Input/output error

Now that qcow2 and qcow handle this case the test passes successfully.
