Fix creating of RRect in SkiaRE

Concat already moves of the layer to the correct position, so the current
origin is already moved. When we draw RRect,  we need to draw something
at position 0, 0, size of layer, which is stored in layer->geometry.boundaries.

Test: Open DialogActivity application. Observer the correct position.
