lsa.idl: define lsa.ForestTrustCollisionInfo and ForestTrustCollisionRecord as public structs

For Python bindings PIDL wants the struct to be defined as public if we
want to use __ndr_print/pack/unpack.

Define the [public] attribute to ForestTrustCollisionInfo/Record to
allow easier debugging when there is collision in establishing a trust.

This change does not affect C code as NDR functions are always
generated, only not exposed in Python bindings.
