Switch Pepper Linux to use shared USB<->native key conversion table.

Switch Pepper Linux to use shared USB<->native key conversion table.

This fixes issues with the Linux table lagging behind the shared version, and:
- Marks the UsbKeycodeToNativeKeycode helper "inline", for now, to avoid the warning on unused static functions, and since it is sufficiently simple to make sense to inline.
- Tweaks the types of the array iterator in the other platform-specific implementations.
