fix #4 (really): use -device and -netdev options instead of -redir

The correct arguments to qemu are

	-netdev user,id=ethernet.0,hostfwd=tcp::5555-:1522,hostfwd=tcp::9999-:9,hostfwd=tcp::17010-:17010,hostfwd=tcp::17013-:17013
		to forward several host ports to the guests ports on ethernet.0
	-device rtl8139,netdev=ethernet.0
		to define the emulated hardware of ethernet.0

They are both required and the netdev's value of the -device option
must match the id's value of the -netdev option.
