qemu: Don't try to find compression program for "raw" memory images

Browse Source 
There's nothing to compress if the requested snapshot memory format is
set to 'raw' explicitly. After commit 9e14689ea libvirt would try to
run /sbin/raw to process the memory stream if the qemu.conf option
snapshot_image_format is set.
