i965: setup sized internalformat for MESA_FORMAT_R10G10B10A2_UNORM

Commit d2b60e433e5 introduced restrictions (as per GLES spec) on the
internal format. We need to setup a sized format for the texture image
so framebuffers created with that are considered complete.

This change fixes following Android CTS test in AHardwareBufferNativeTests
category:

   SingleLayer_ColorTest_GpuColorOutputAndSampledImage_R10G10B10A2_UNORM

Fixes: d2b60e433e5 ("mesa/main: R10G10B10_(A2) formats are not color renderable in ES")
