[PATCH 1/3] struct_union_enum_specifier: set MOD_TOPLEVEL if toplevel(sym->scope)

[Oleg Nesterov <oleg@redhat.com>]

With this change dissect can know the scope of SYM_STRUCT/UNION/ENUM,
see the next patch.

Note that MOD_TOPLEVEL can be set even if struct/union/enum type is
private and bind_symbol() is not called.

IIUC nobody else looks at SYM_STRUCT->ctype.modifiers, "make check"
doesn't show any difference.
