dmx/examples: Fix missing key_click_percent assignment.

Thanks to gcc's -Wunused-but-set-variable, stop ignoring the percent
parameter, and add it to the XKeyboardControl structure before the
XChangeKeyboardControl call.

This warning goes away accordingly:
|   CC     xbell-xbell.o
| xbell.c: In function ‘main’:
| xbell.c:74:22: warning: variable ‘percent’ set but not used [-Wunused-but-set-variable]
