Kill fluff about how route(8) is of limited usefulness

Don't say that route(8) is mostly useful to set up a default route,
which is almost a lie.  What's more, I'm not sure new users struggling
with route(8) should be pointed to ripd(8) (sic) or bgpd(8) as
a solution to their problems.  ok benno@ kn@
