Linux/BSD: Modify only keypad keys

Browse source 
The `keycode` field of `InputEventKey` is supposed to be "unshifted";
That is, what the key would output if no modifier keys were pressed.
This should match what's written on the key label, but `Key` enumerates
also all keypad keys, which require a modifier. We thus require some
extra checks for them.

Note that this can still allow "stuck keys", but that's an even deeper
problem.
