neighbour: add support for NUD_PERMANENT proxy entries
As discussesd before in [0] proxy entries (which are more configuration
than runtime data) should stay when the link (carrier) goes does down.
This is what happens for regular neighbour entries.
So lets fix this by:
- storing in proxy entries the fact that it was added as NUD_PERMANENT
- not removing NUD_PERMANENT proxy entries when the carrier goes down
(same as how it's done in neigh_flush_dev() for regular neigh entries)
