udev: Add hotplugging for VLAN devices

Browse Source 
The VLAN devices will now automatically be created after
a parent device has been added.

Mainly this will resolve a race-condition between udev
initialising the network adapters and sysvinit running
scripts that will do the initialisation of the VLAN.
