[PATCH 7/9] use connect instead of bind

[Jens Osterkamp]

modifies the setup of the netlink socket in drv_cfg.c to use pid 0 instead
of the processes pid.
Also replaces bind with connect to allow the reception of netlink messages
from libvirt.
Preparation patch for communication between libvirt and lldpad.
