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.
