[PATCH] KVM test: tests.cfg.sample: add params to qemu command line properly

[Lucas Meneghel Rodrigues <lmr@redhat.com>]

There's a small bug on the qemu sample testset for KVM autotest:
We need to append -enable-kvm as extra params to the qemu command
line, not replace all extra params. Small bug, renders the unattended
install unusable for folks trying qemu instead of qemu-kvm.

Thanks to Kevin Wolf for having found this problem.
