As Marek noted, the GL_RGBA + GL_UNSIGNED_INT_2_10_10_10_REV type
combo is also good for readback of BGRX1010102 framebuffers, not
only for BGRA1010102 framebuffers for use with glReadPixels()
under GLES, so add it for the GL_IMPLEMENTATION_COLOR_READ_TYPE_OES
query.
Successfully tested on gallium r600 driver with a (quickly hacked
for RGBA 10 10 10 0) dEQP testcase
dEQP-EGL.functional.wide_color.window_1010102_colorspace_default.
