mesa: allow GL_TEXTURE_CUBE_MAP_ARRAY case for glCompressedTexSubImage3D()

Browse source 
Since s3tc works for cube maps and 2D arrays, it should also work for
cube arrays.  NVIDIA's driver supports this too.  Seems like the spec
should say this.

This is a minor follow-on fix for the commit "mesa: fix up some texture
error checks".
