liblights: Fix variable button brightness code
* Because we're using #ifdef in set_light_buttons(),
defining VAR_BUTTON_BRIGHTNESS to anything, including 0,
results in the button brightness code being enabled
* That results in broken touchkey backlight for devices
that don't override the samsung_lights header, or defined
this macro to 0 in their device's samsung_lights header
* Comment out the macro to correct this logic
