This patch broke qemu-iotests 051 because it neglected to update the
reference output. Not sure if a change of the message was even intended,
but with a error location prefix, the order changes:

-(qemu) QEMU_PROG: -drive if=scsi,media=cdrom: warning: bus=0,unit=0 is deprecated with this machine type
+(qemu) warning: qemu-system-x86_64: -drive if=scsi,media=cdrom: bus=0,unit=0 is deprecated with this machine type

Personally, I would expect the error location or at least the program
name to come first even for warnings.
