devices: Increase the uevent socket buffer size

Depending on the timing, hald may start while ueventd is not done yet
with its initial coldboot. As hald also independently starts its own
coldboot, ueventd netlink socket buffer could get filled quickly and
thus ueventd could lose some uevents.
This is fixed by increasing the ueventd netlink socket buffer size.
