[OE-core] [PATCH] 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;

Apparently, the autobuilder has some magic into it because all the sanity tests
succeeded... So, I don't know why AB tests succeeded but on my machine, and several
others, networking was broken and couldn't connect into the qemu image. If I'm
missing something, please, do not hesitate to correct me. This patch fixes the
issue for me though.

Thanks,
Laurentiu
