Do not set indirect flag on edges from nodes with multiple addresses.

Browse source 
Since tinc now handles UDP packets with a different source address and port
than used for TCP connections, the heuristic to treat edges as indirect when
tinc could detect that multiple addresses were used does not make sense
anymore, and can actually reduce performance.

We are currently examining the edge e right of n from n:
- If e->reverse->address != n->address, then e->to is probably
not reachable for the nodes left of n. We do as if the indirectdata
flag is set on edge e.
- If edge e provides for better reachability of e->to, update
e->to and (re)add it to the todo_list to (re)examine the reachability
of nodes behind it.
