Fabian Bläse 9c11cc7296 fff-babeld: create filter for prefixes used with snat 
If a prefix is used for a client interface utilizing snat, it shall
not be publicly reachable, so it can be reused across multiple routers.

To prevent such prefixes from leaking, create appropriate babel filters
if snat is used.

Fixes: #196
