5f47182 fix has regressed in 1.2-beta1

[Tore Anderson <tore fud no>]

dcbw asked me to send this to the list:

When clatd starts up, it creates a new interface (not managed by NM)
and adds a static route bound to it. NM immediately removes that route,
breaking clatd. Of course, NM has no business deleting routes from
interfaces it's not controlling. The bug (at least the previous
incarnation of it) is described in more detail in bgo#740702.

Debug log from NM when starting clatd here:

Output from "ip monitor | ts" at the same time here:

http://filebin.net/fr71uh512e/ip-monitor.txt

It's the "Deleted 2a02:2121:1:3389:da32:8a93:6378:0 dev clat" line that
should never have been there.

Hope this can be fixed before the 1.2 final release.
