Actually set TYPE_PACKED for type_recordpacked

When bootstrapping with --enable-checking=no you'll get:

gcc/rust/backend/rust-compile-type.cc: In member function
‘virtual void Rust::Compile::TyTyResolveCompile::visit(const Rust::TyTy::ADTType&)’:
gcc/tree.h:2312:59: error: statement has no effect [-Werror=unused-value]
 2312 | #define TYPE_PACKED(NODE) (TYPE_CHECK (NODE)->base.u.bits.packed_flag)
      |                           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~
gcc/rust/backend/rust-compile-type.cc:315:7:
  note: in expansion of macro ‘TYPE_PACKED’
  315 |       TYPE_PACKED (type_record);
      |       ^~~~~~~~~~~

We need to actually set a value for the packed_flag.
