KVM-test: Only add tftp option when using user nic mode

qemu-kvm man page:
...
-tftp dir
      When using the user mode network stack, activate a built-in TFTP server.
      The files in dir will be exposed as the root of a TFTP server.  The TFTP
      client on the guest must be configured in binary mode (use the command
      "bin" of the Unix TFTP client). The host IP address on the guest is as
      usual 10.0.2.2.
