ozone: evdev: Squelch unknown key errors for mouse & digi from gestures

These are uninteresting because they are not keyboard keys and because
they are redundant with button presses & MT contacts in gestures. We
could possibly pass on the "tool" used (BTN_TOOL_*) for touch, but we
currently don't use it.

BUG=none
TEST=ran chrome on link_freon, no more "unknown key" errors

LGTM

We'd still get unknown key errors from joysticks and gamepads, though?

Yeah, leaving those for lack of a better idea. If one gets plugged in, it
probably won't work, but there'll be obvious warnings.
