Revert "r300g: remove L8_UNORM from colorbuffer formats"

This reverts commit fc427d23439a2702068209957f08990ea29fe21b.

At least xorg uses this, and just because something is not used in
OpenGL is *never* a valid reason to remove functionality from Gallium.
If something lacks a test, go add a test, don't remove features.
