ozone: evdev: block LS2208 barcode scanner as a keyboard

This barcode scanner (as with many others) works by pretending to be a
keyboard and typing out the barcodes it scans. This prevents the
on-screen keyboard from appearing on devices without an actual keyboard
plugged in.

Bug: 1004645, b:141515578
Test: check scanner works, and that VK appears when appropriate
