NAT PPTP Set-Link-Info messages in the PAC->PNS direction.
These are sent by Windows Server 2003.

Note that Set-Link-Info messages do not need to be NATed in the
PNS->PAC direction, since we never NAT the PAC call id.

Tested for linux-2.4.29 only, but should also apply to both 2.6
versions in patch-o-matic-ng.
