test: rework run_qemu
It tries to find a suitable QEMU binary and will use KVM if present. We can now configure QEMU from outside with 4 variables : - $QEMU_BIN : path to QEMU's binary - $KERNEL_APPEND : arguments appended to kernel cmdline - $KERNEL_BIN : path to a kernel Default /boot/vmlinuz-$KERNEL_VER - $INITRD : path to an initramfs Default /boot/initramfs-${KERNEL_VER}.img - $QEMU_SMP : number of CPU simulated by QEMU. Default 1 (from Alexander Graf's script: http://www.spinics.net/lists/kvm/msg72389.html)
