energy_probe: send signal SIGINT to caiman
ARM energy probe sends SIGTERM to caiman, this signal can be missed by
caiman due caiman has not registered signal handler for SIGTERM. On the
other hand, caiman registers signal handler for SIGINT, this patch is to
change to use signal SIGINT to notify caiman.
