st: fix st_choose_matching_format to ignore intensity
_mesa_format_matches_format_and_type() returns true for
GL_RED/GL_RED_INTEGER (with an appropriate type) into an intensity
mesa_format.
We want the `red`-based format instead, regardless of the order we find
them in our walk of the mesa formats list.
