kvm tools: Add missing space after kernel params

Add missing space so that user-provided kernel params
will be properly concatenated to default params.

Instead of just adding a space at the end, add it with
a separate strcat(), since it's not the first (and wouldn't
have been the last) time a space wasn't added.
