input_id: Identify scroll-wheel device on Trust TB7300 tablet as keyboard
The Trust TB7300 (relabelled Waltop?) tablet has a scrollwheel which shows
up as a /dev/input/event# node all by itself. Currently input_id does not
set any ID_INPUT_FOO attr on this causing it it to not be recognized by
Xorg / libinput.
This commit fixes this by marking it with ID_INPUT_KEY.
