Khronos has apparently decided that depth textures with sized formats

Ian is proposing changes to ARB_internalformat_query which will make
this actually legal and consistent.
A similar problem exists with GL 4.2, but we're going to ignore that
for the time being.
Tested on Ivybridge: no Piglit regressions; fixes 4 es3conform tests:
- depth_texture_fbo
- depth_texture_fbo_clear
- depth_texture_teximage
- depth_texture_texsubimage

We probably could have done this in core Mesa, but I think this is okay
for now. I pushed a version of this patch with my R-b to the gles3 branch.
Yeah, I was going to make a core Mesa helper function until I realized
it was so little code.
