Fix brightness keys on MSI Wind U-100

The MSI Wind 100 generates ACPI/input events on the LNXVIDEO input device. On
top of that, the video module/BIOS synthesize some extra event on atkbd as an
echo of actually changing the brightness.

Ignore the wrong and useless atkbd ones, to avoid event loops.

Many thanks to Hans de Goede for tracking this down!
