cleanup redundant interfaces from iftable to avoid excessive LinearAlloc use

In deep interface hierarchies super-interfaces are recursively concatenated
to create the iftable. There was no checking for duplicated entries so that the
iftable could get pretty large with just a few layers of interfaces up to the
point where the LinearAlloc was exceeded completely.

This change scans the iftable linearly for existing entries before it adds another
one.
