[iproute] man: ip-route.8: Fix ENCAP references in synopsis

The different encapsulation types are described in ENCAP_*
non-terminals, but ENCAP definition lists them without the ENCAP_
prefix. Fix this for consistency.

This looks good but do we have another inconsistency with regards
to ENCAP and ENCAPTYPE ENCAPHDR (further down).

Glancing over the file the following also seem inconsistent:

* NH / NEXTHOP
* SCOPE / SCOPE_VAL

I didn't check very thoroughly so there could well be more.

Well, strictly speaking yes. If I want to know more about NH listed in
synopsis I can't find it further down. Though its description in
'nexthop' is incomplete, as well.

My personal focus is that non-terminals in synopsis are defined in there
as well, otherwise I can't parse and the thrown exception is hard to
clean off my screen. ;)

My assumption (actually what *I* do) is to search for terminals in order
to get more info. For instance, I would search for 'nexthop' or 'encap'
not 'NH'.

I guess the broader question is about the scope of non-terminals in
synopsis and description sections - I don't necessarily consider them
related.

Of course feel free to fix what you don't like, I'll review and (N)ACK
if you put me in Cc. :)

Cheers, Phil
