Do not expose stub types to Python
dwarf2read.c will create stub types for Ada "Taft Amendment" types.
These stub types can currently be exposed to Python code, where they
show up as TYPE_CODE_VOID types (but that, mysteriously, can sometimes
be used in other ways).
While it's possible to work with such types by using strip_typedefs,
this seemed unpleasant to me. This patch takes another approach
instead, which is to try not to expose stub types to Python users.

* python/py-type.c (type_to_type_object): Call check_typedef
for stub types.
