glx: Only assign 8 bpc fbconfigs for composite visuals.
Commit 91c42093b248 ("glx: Duplicate relevant fbconfigs for
compositing visuals") adds many new depth 32 fbconfigs as
composite visuals. On a X-Screen running at depth 24, this
also adds bgra 10-10-10-2 fbconigs, as they also have
config.rgbBits == 32, but these are not displayable on a
depth 24 screen, leading to visually corrupted desktops
under some compositors, e.g., fdo bug 104597 "Compton
weird colors" when running compton with
"compton --backend glx".
Be more conservative for now and only select fbconfigs with
8 bpc red, green, blue components for composite visuals.
Fixes: 91c42093b248 ("glx: Duplicate relevant fbconfigs for
compositing visuals")
