vrend: bind correct layer for texture arrays in gl blitter

For texture arrays, the layer is stored at blit.{src,dst}.box.z.
In those cases, we need to go through the same path as we already do for
GL_TEXTURE_CUBE_MAP.

Fixes piglit's spec@ext_texture_array@copyteximage {1d_array,2d_array}.

Tested on both GLES and GL backends.
