efl_ui_layout: prevent needless calls of elm_layout_sizing_eval

`elm_layout_sizing_eval` is implemented for only classees that inherit `Elm.Layout`

This patch will fix following error log
```
/EFL ( 3158): eo<3158> ../src/lib/eo/eo.c:579 _efl_object_call_resolve() in ../src/lib/elementary/efl_ui_layout_legacy_eo.c:37: func 'elm_layout_sizing_eval' (1692) could not be resolved for class 'Elm.Rpanel'.
```
