[event-input] Ignore camera events in volkey probe. MER#1634

The evdev nodes that emit other events in addition to volume key events
are subjected to volume key input policy only if all of the additional
events have been whitelisted.

At least Onyx devices emit camera events such as KEY_CAMERA_FOCUS from
the same device node as KEY_VOLUMEDOWN and KEY_VOLUMEUP.

As camera keys are unlikely to be needed while display is off, they should
be relatively safe to be ignored while probing for blockable volume key
input devices.
