Efl.Canvas.Vg.Object: Fix wrong render area

Summary:
When determining the size of the ector buffer,
it was used the smaller of the object's geometry or path_bounds.
However, because of that, path worked as absolute coordinates.
path_bounds should be relative to geometry of object.

Test Plan:
{F3900444}
original
{F3900445}

before
+ evas_object_geometry_set(vg, 100, 100, 200, 200);
{F3900447}

after
+ evas_object_geometry_set(vg, 100, 100, 200, 200);
{F3900448}
