Mark outbound initiated server to server connections as local.

Mark outbound initiated server to server connections as local.

This fixes an issue where if a disconnect packet is received by the
server for an outbound silc connection (i.e. a server to server link)
and there is an outstanding async operation, such as an SKE or
connection auth, the server will corrupt the heap due to not properly
calling the async abort routine.

This issue would typically happen when we have a silcd setup to connect
to a remote router server, where both ends of the connection have public
keys configured, but the initiator server's IP is wrong.  In this case,
we will get past key exchange and then fail at the connection auth
packet, typically crashing the initiator silcd after heap corruption.
