Eolian/Generator: enable forcing return type as void.

For get properties, if only one parameter is given, the generator sets this one as return type.

There are cases where this parameter must stay a parameter (legacy API).

For example, elm_thumb_compress_get must be like:
void elm_thumb_compress_get(const Eo *obj, int *compress).
Eolian was generating the function as:
int elm_thumb_compress_get(const Eo *obj);

By setting "return void;" in the .eo file, you force the function to
return void.
