man: ip-neighbour.8: Document all known nud states

Not sure how useful they are in practice, but as 'ip neigh' supports
|
|
|
049c96 |
setting them all, they deserve to be described as well.
|
|
|

|
|
|

While at it, also add a missing layer of indentation to the subordinate
|
|
|
049c96 |
nud state list.
