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.
