LinuxKMS: Add XRGB8888 fallback when no DRM plane formats found

Browse source 
Instead of failing when no plane formats are detected, fall back to
XRGB8888 which is widely supported. This prevents crashes on systems
where plane enumeration fails while still allowing the display to
function with a common pixel format.
