Russ Cox 68aaf2ccda runtime: make scan of pointer-in-interface same as scan of pointer ...

The GC program describing a data structure sometimes trusts the
pointer base type and other times does not (if not, the garbage collector
must fall back on per-allocation type information stored in the heap).
Make the scanning of a pointer in an interface do the same.
This fixes a crash in a particular use of reflect.SliceHeader.

Fixes #8004.
