vrend: Correctly set pack alignment for three component textures

For rgb8 and rgb16 textures the element size is 3 and 6 respectively,
and the packing must correspond to the component size (1 and 2).

Fixes:
  dEQP-GLES3.functional.texture.specification.basic_teximage3d.rgb16i_3d
  dEQP-GLES3.functional.texture.specification.basic_teximage3d.rgb16ui_3d
  dEQP-GLES3.functional.texture.specification.basic_teximage3d.rgb8i_3d
  dEQP-GLES3.functional.texture.specification.basic_teximage3d.rgb8ui_3d
