scanner: Only mark structures and unions as out-caller-allocates

These are the only things for which we expect native values to be
preserved; for e.g. flags and integers, we expect bindings to convert.

The particular rationale for this patch is to avoid flagging flags (sic)
as (out caller-allocates).
