ndp: Set router lifetime to 9000s instead of 3600s

Browse source 
Seen while testing: lifetime expires while we're flooding a tap
interface with UDP packets, the router advertisement comes too late,
and the kernel drops the default router in the namespace. This
should only affect testing, so go for the maximum allowed value,
that is, 9000 seconds.
