Description of problem:
(Reporter: Evaggelos Balaskas)

> # virt-sparsify -v --compress winxp.img winxp.img.spars
>
> qemu-img convert -f qcow2 -O 'raw' -c '/VM/sparsify10f031.qcow2'
> 'winxp.img.spars'
>
> qemu-img: Compression not supported for this file format
> virt-sparsify: error: external command failed: qemu-img convert -f
> qcow2 -O 'raw' -c '/VM/sparsify10f031.qcow2'
> 'winxp.img.spars'

If the output format is a format which doesn't support
compression (eg. raw), then virt-sparsify should give a
clearer error message.

Commit 43369e1bd4d98acf1cce6eb0216dcdb43d43bf1b
changes the error to say:

virt-sparsify: error: --compress cannot be used for raw output.  Remove 
this option or use --convert qcow2.
