Subject: ip route JSON format is unparseable for "unreachable" routes

Hi,

I created a couple "unreachable" routes on one of my systems, like such:

> ip route add unreachable 10.0.0.0/8     metric 255
> ip route add unreachable 192.168.0.0/16 metric 255

Unfortunately this results in unparseable JSON output from "ip":

> # ip -j route show  | jq .
> parse error: Objects must consist of key:value pairs at line 1, column 84

The offending JSON objects are these:

> {"unreachable","dst":"10.0.0.0/8","metric":255,"flags":[]}
> {"unreachable","dst":"192.168.0.0/16","metric":255,"flags":[]}
"unreachable" cannot appear on its own here, it needs to be some kind of
field.

The manpage says to report here, thus I do :) I've searched the
archives, but I wasn't able to find any existing bug reports about this.
I'm running version

> ip utility, iproute2-ss190107

on Debian Buster.

Regards,
Michael.
