runqemu: fix networking issues
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; (From OE-Core rev: a286514e2311f52b54d3571dbac6d34aff39e591) Signed-off-by: Laurentiu Palcu <laurentiu.palcu@intel.com> Signed-off-by: Saul Wold <sgw@linux.intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
