st/mesa: add fallback pipe formats for (compressed) R, RG formats
If we don't find an exact PIPE_FORMAT_x for a GL_(COMPRESSED)_RED/RG format, try uncompressed formats. We were already doing this for the RGB(A) formats. Fixes piglit arb_texture_compression-internal-format-query test. NOTE: This is a candidate for the stable branches. Reviewed-by: José Fonseca <[email protected]>
