Fix default route with libnl3.8+

Since libnl3.8, the nl_addr_parse function does not return 'none' anymore for 'default', but it returns a 0.0.0.0/0 addr. thom311/libnl@0c0aee8 But since we depend on that value in vdsm, it never reports a default gateway anymore, causing networks to be out of sync. So next to 'none' we also check for '0.0.0.0/0' or '::/0'. Signed-off-by: Jean-Louis Dupond <[email protected]>
