iproute2: Remove "monitor" from "ip route help" output

$ ip route help 2>&1 | grep monitor
ip route { add | del | change | append | replace | monitor } ROUTE
$ ip route monitor
Command "monitor" is unknown, try "ip route help".

(I guess what was really intended is "ip monitor route", so just remove
the argument from the help output.)

While at it, also drop all non-existant (route,link,netns) monitor
arguments from the ip(8) man page.
