Ensure #transform_values of HWIDA to return HWIDA

Browse source 
On Ruby 2.4, naitive `Hash#transform_values` is implemented.
`Hash#transform_values` uses an instance of Hash (`rb_hash_new`) to
collect returned values of a block.
For ensuring `#transform_values` of HWIDA to return HWIDA, we should
define `#transform_values` on HWIDA.
