[PATCH v2 1/1] runqemu: fix networking issues

[Laurentiu Palcu]

After switching from ifconfig to ip, networking stopped working. This
commit contains the following fixes:

 * set a decent broadcast address for the tap device;
 * bring up the device;
 * add the route using ip tool instead of the old route tool;
