In preparation to make options VIMAGE operational, where needed,
initialize / release netgraph related state in iattach() / idetach()
functions called via the vnet module registration / initialization
framework, instead of initialization / cleanups being done in
mod_event handlers.

While here, introduce a crude hack aimed at preventing ng_ether to
autoattach to ng_eiface ifnets, which are also netgraph nodes already.
